Out West

I wasn't sure where to post this question, but planning a trip out to Montana to photograph the the Grand Tetons, (WY) and up to Yellowstone and on to Glacier National Park.

I know there's readers from all over the country that reads these reviews and would like advice on the most economical places to stay with the best photo oportunities.

I'm taking my D70, D300s, 70-200vr with TC-17, Sigma 105 Macro, 50 1.8 and kit lens.

Any and all advice is appreciated.

Thanks
