Returning after three years and I don't remember the supply options on the east side. Particularly interested in MSR and Jetboil fuel purchases, grocery and freeze-dried selection. Of course if we do need to shop in Great Falls, I guess Scheels is the place. I like to support local shops though as in the long run it helps us all out.
Just car camping except for Sperry Chalet, but we'll do some standards and a few long day hikes.
