I heard Idaho Falls was cool, chatted with some cool folks, but i'm not really sure. I'm new to the northwest, i'm as far east as someone in the north west can be and still be in the north west, so sadly i'm no where near Idaho, so for sure, I can not tell you about the hippy scene in Idaho, I've had hints it's around though.
Hey, I'm in Idaho and am also lookin for some kind people in the area. I'm south of Boise about 45 miles I think, Mountain Home. Nice to meet you all.
