Are you kidding, Phil? I have three kids...son and his wife are living in a single wide trailer older than ours with a little one in a wheelchair, older daughter is in a rental duplex with her 10 year old son, and we are living in a 1976 single wide trailer. So first order of business would to build a totally handicapped accessible house for Kenny and Jenny, a new house with a huge yard for my gardening fanatic daughter and her partner in dirt, Evan, and a real house for me and Ken - preferably a beautiful straw bale house. I'd also buy the lots directly across the streets from me - one on the north side and the other on the east side - so nobody would build a big two story house there and take away the mountain views I get from those windows. Then Little Diane and Dustin would get a new house back there in Sioux Falls, and so would Jamie and Rachel in Chicago.
Next would be a handicapped accessible van for Kenny and Jenny and one for us, with all the bells and whistles and a new car for Tam that doesn't break down at 7:00am when it's 3 below zero. Then I'd go on a shopping spree to get Kendra the shoes and socks she needs so badly, made for kids with AFO/KAFOs. Know how much socks are for Kendra? $30.00 a pair! Shoes? How about starting at $65.00! No, wait - even better! I'd buy the companies that make them and then provide them free to every family who is expected to pay as much for shoes and socks as they spend on groceries for a week! Oh, and wheelchair friendly winter coats, too - those are also way too expensive for us! And college funds or trade school funds for all the grandkids and great grandkids.
After that was done, a million would go to research on childhood cancers, 2 million for research and support for families of kids with Epidermolysis Bullosa, a million for Marfan's research and another million for research into regenerating nerves in kids with Spina Bifida. Then I'd build a huge park for all kids, but with emphasis on letting kids with disabilities enjoy it safely too! Wheelchair accessibility to every spot on the place, petting zoos, ropes for blind kids to follow and explore the surrounding forests, less sensory intense areas for kids with ADD and Autism....oh, I could make it really something - and free! Ponds for fishing and wildife, and I'd call it KLB Ranch - for Katie LaVonne and Kendra LeeAnne.
I'd renovate old, abandoned buildings and provide homes for folks who need a little help getting back on their feet. I'd buy a huge lot, landscape it nicely and make it a low cost mobile home park for folks who prefer or can only afford a mobile home. A Disney cruise for the whole family.
