[Polar Bear]

My wife and I want to explore the possibility of at least portions of the summer living elsewhere. We're not interested in being true snow-birds...owning a second home or anything like that. We would like to rent somewhere for anywhere from one to three or four months. We're not interested in a house-swap. (Although we might be interested in house-sitting, if anybody has any experience with that.)

We live in TV and would like to spend some summer time a bit north, ideally in or near the mountains and within reasonable reach of a bit of civilization for shopping and change of pace occasion. Eastern US would be good, but we'd also consider Rocky Mountain, Yellowstone, all those sorts of areas. We'd at least look at almost anything in the continental US.

Anyway, can anybody recommend such a place, or a service to help us out? Possibly a realtor? Travel agent? Something else?

All input considered. Thanks in advance.
