If I may ask, what prompted your move from Hawaii to Montana? Did you vacation there and fall in love with it? By the way, I love your new avatar. What's not to love about a picture of a beautiful young lady by a beautiful blue lake?
A number of factors played a role in our decision to make the move.
First and foremost, economic factors. We owned a 5 bedroom home in Hawaii with very little land around it and were paying $3200 per month in mortage payments. We were able to sell our home there and buy a similar sized 6 bedroom home on a small farm just outside of Kalispell, MT, and pay for it outright (no mortgage) with cash left over. In addition, the cost of goods here is about half of what it was in Hawaii. In addition, the taxes continue to mount in Hawaii due to a number of issues including the rail project, which is now estimated to be at least 20 years in completion and will run 10 billion dollars over budget (the truth is it will take longer and cost more); the slow but sure cutting of the military (10,000 cut recently, 60,000 more in the near future) which is a major blow to Hawaii's economy; and the fact that the homeless problem has reached epidemic proportions in Hawaii with homeless tent cities spread out all over the public beaches where the huge number of homeless leave them trashed and severely hurting tourism which is a major industry in Hawaii. Unfortunately the tax payers are having to shoulder the load of all this. Furthermore, if our country experienced a major economic collapse so that shipping from the mainland shut down, Hawaii's grocery stores would be completely empty within a week or two (already when there is a tsunami or hurricane threat, the rice and bottles of water are gone within a day or two and the gas station lines are a mile long). And there is no way that Hawaii's natural resources could even begin to support its population.
Second, crowd and traffic factors. My son-in-law was teaching at a high school about 12 miles from our home, and on many days it would take him 2 hours to drive to work and another 2 hours to drive home. We wanted to get away from all the crowds and traffic in Hawaii and move to a low density population state.
Third, climate change in Hawaii. When we first moved to Hawaii 23 years ago, most of the days we had trade winds which bring cooler temperatures and lower humidity. Only a few days during the summer would we get Kona winds which bring higher temperatures and high humidity, but over the past few years that has changed. This past year we had more Kona wind days than trade wind days and this past summer we experienced a record number of days with temperatures in the 90s (with around 90% humidity) forcing us to run our air conditioners. Our last month's electric bill in Hawaii was over $800, compared with $60 for our first months electric bill in Kalispell (economics again). In addition, the Kona winds also bring VOG (volcanic smog) over from the lava vents on the big island and this has gotten much worse since a second volcanic vet opened up a couple of years ago. VOG can create respiratory problems even for normal lungs and with both my son-in-law and my granddaughter having asthma, it was a constant struggle for them. And long term meteorlogical forecasters say that these climate changes are here to stay in Hawaii (Hawaii is going to become the next Guam).
In conclusion, we wanted to move to a low density population area with lots of natural resources where we could buy a small farm with no mortgage, where the cost of living was much lower than Hawaii, and where summers were cooler and less humid and air and air quality was better than in Hawaii. I had visited the Rocky Mountain states in the past and our family had been to Alaska on several occasions so we narrowed the search down to the three states with the lowest population density--Alaska, Wyoming, and Montana. We seriously considered Alaska, but finally backed out due to the fact that property prices and the cost of living, while quite a bit lower than Hawaii, was still quite a bit higher than most of the 48 mainland states. We decided to go with NW Montana over Wyoming as NW Montana has considerably more natural resources (water, timber, agriculture, etc.) than any area in Wyoming. None of us had personally been to Kalispell or Flathead County but my wife and I both have Aunts and Uncles who have visited in this area in their RVs on a number of occasions, loved it here, and all told us that Kalispell was the place to go. They would have retired in this area themselves had their kids and grandkids not all lived in Texas. So we researched the area thoroughly, took their advice, and here we are with our own farm (debt free) in NW Montana.
