Some great info guys.
As far as Colter Bay or Gro Ventre...I see they're first come, first served. Anybody have trouble getting a site? With a pretty big rig I'm worried about getting all the way up there and finding nothing. I've only boondocked with it, so a formal campground will be a first for us....and we're planning to be up there the week of 7/4.
As far as crossing into Canada...I'm totally open to suggestions. I haven't even looked at a map yet so have no idea. Sounds like the suggestions for east Glacier would be good and just drive from there (without the trailer).
And yeah...I don't plan to spend lots of time in the campgrounds...just need a place for the rig.
If the place mentioned with full hookups is Teton Range Resort, they want 99 per night! Why bring the rig for that price?
