In mid life I took a 6 yr retirement I guess for practice and lived in a tent and bummed around the country running traplines and hunting through the fall and winter. At 42 I decided to go back to work and put together a decent grubstake for the next retirement so I wouldn't have to bother with the odd jobs in the off season.
We retired to the WA coast, it is never hot, never really cold and you don't have to shovel rain. Duck hunting is incredible, the forests abound with bobcat, mountain lions, coyotes, bear, elk and deer.
My wife has her own motor home when she has the notion she heads to warmer climates in the winter. After hunting season is over up here, I hunt upland from the coast here to the Dakotas and waterfowl all over WA plus my passion for hunting coyotes everywhere. I head south hunting coyotes through NV, UT, AZ and NM catching up with her in lat Feb. spending a month or so basking in the sun sightseeing and coyote hunting before we make a slow trek back to WA to enjoy the summers here.
Find a nice low maintenance home base that you could go to if things get tough, doctors, close stores etc. and get mobile, I have a van set up with a bunk that I can hunt out of and live in, I've met hunting partners all over the west and everywhere you go there is so much interesting stuff to see. One year my wife and I spent much of the spring pursuing the best chili cheeseburger in NM(Sparky's in Hatch, NM). It is surprising all the folks from around the country that we've met on the road also. Do you know there is a RV campground outside of Douglas, AZ that is a trap shooting mecca, The rifle range outside of Tucson has RV sights and there is free camping on BLM land all over the west.
