all those states have that common element that your looking for, that wild independent flavor........except one,perhaps? I don't see Indiana in that mix. The western states are like a big, beautiful fruit basket . Lumping Indiana in that is like throwing a pickle in the basket. Still very edible but a different taste. Your best states for wheeling have the most public lands. States like Arizona, Utah and Nevada have a nearly unlimited
amount of unrestricted travel. 82% of Arizona is owned by some government agency, almost all of it accessible. Indiana ranks 39 out of 50. Top ten are Alaska, Idaho, Nevada, Colorado, Utah, Oregon, Wyoming, new Mexico and even California. Washington is still in the top ten at tenth place .
I lived in Spokane a year and was disappointed in the lack of nearby places to wheel and camp. I usually crossed over to Idaho. I suppose Az spoiled me. I moved back to Az. Your worst case in Az is living in Phoenix. The city covers over 100 square miles so if you're in the center you drive an hour before the journey starts. Nice thing is that you've got winter camping in the desert within 20 miles of the city and depending which direction you go
and summer camping in pine forests are 50~100 miles away. For me, in Globe, I can drive 30 minutes and have a secluded campsite either in a desert or forest
