That sounds depressing! But it's not my experience at all in the Midwest. I love the seasons. Summer can get a little hot, but there is still a lot to do around here. Winter is very fun to from cross country skiing, to fat tire biking, bonfires, and snowmobiling. I go out regularly in anything as low as -30F to -40F as long as I am dressed properly. Then we get Fall/Spring which are very special.
Honestly I've been to SF a lot and I find California down right dreary and boring!
Many in our area are farmers and they are a lot tougher than your post suggests.
The truth is healthy food is insanely expensive. We spend over $1000+/mo for two people. I know families with kids that eat on less than half that by eating less healthy.
