This summer (probably early-July) my father and I will be taking a road trip to Montana from Maine. Our main goals are to visit as many hot springs and national parks as possible, and enjoy the beautiful nature in that area. We're taking our beat up, but somehow still working, 1997 Honda. We're hoping to do this with as little money as possible, and spend as much of our downtime as possible backpacking/camping. We WILL be trucking our kayak along too. This will be our first major road trip together. First off, I'd like to know from people who have done similar journeys about how long it might take. We aren't very time restricted, but I don't necessarily want this to take a month either. I'd like to know about any place in particular you think we should stop, any secluded, natural, undeveloped hot springs you know of, and tips for money-saving.
Thank you so much, and best of luck with all your adventures. Thinking positive vibes :)
