I don't think it is all that difficult to have a vegetable garden if you really want one. When I first moved to Washington I could barely afford the rent on my apartment. Still I had a vegetable garden. I went dumpster diving for old houseplants that people had tossed. I grew Herbs, lettuce and basil on my deck in these. I also would ride my bike to Marymoor park where they had a Peapatch. I made friends with several people who had patches there and offered to care for their gardens in exchange for some space to grow some of my own.
Now I am not poor, but I am frugal at times. Mother Earth had free entrance for kids, and I paid $10 for a weekend pass for myself. Parking was free and I brought in food for my kids and myself. I did give $5 to each kid to spend. I thought it was a fantastic deal compared to the Evergreen Fair we attended last summer. Between pArking, entrance fees, 2 rides for each of my 2 kids, and lunch; we spent over $100 in the 2 hours we were there. I was upset that all the drinking fountains had been disabled, forcing fair goers to pay $2 for a small bottle of water. Between the crowds and the outrageous Prices charged, we left early and everyone was unhappy. I was not willing to pAy $6 so we could have a little water; I had scraped the bottom of my purse for enough coins for lunch.
