North Idaho Panhandle...........hands down.
Cheap real estate, gorgeous country, large lakes, small lakes and more streams, rivers and "criks", than one can even FIND, let alone FISH, in at least the 16 years I lived in that area!
Every place, has its own "down side", and this area of course, is no exception. Winters can be worse, than "brutal", as when I left, on Jan. 13th, '93 it was minus 30 below and no wind. (thus, a true temp, not a wind chill temp).
But, I also learned I could "set my watch" by the seasons............. never snowed, before Thanksgiving Day.. stopped the cold and the snow, never later than the end of March. Rains, off and on, until the middle of May, then a long, beautiful, summer until late October!
Hunting for elk, deer and pheasant, etc. was never more than a tank of fuel away, (that's round trip!), and fishing "Blue Ribbon Waters", was only a day trip, at best. 90"% was less than 50 miles.
If you get into the "political side" of things, the "Liberal Front arguments", "Radical Thinkers"...then yes........ Idaho has "It's own problems", but I think a place to live, anyplace you choose to retire, and/or, move to........is going to have it's distractions and problems. You just have to sort of; "Weigh what you're after-versus what you're wiling to put up with to be there"!?
