My buddies and I are in the process of planning a trip out west from Pennsylvania. We are tossing around Montana, but are open to any idea's.

We would like to do the trip as cheap as possible, we do not need the comforts of life while staying. If we decide to come to Montana, we are going to get ranger cabins to stay in for around 35 dollars per night.

Does anyone have any suggestions on which ranger cabins to stay at in Montana or private cabins for rent (cheap)?

How is fishing in Colorado or Wyoming?

I am open to all suggestions. We just want to catch one fish each and have an awesome time.
