My boyfriend are planning to do a 3 weeks road trip from Ohio to Washington in July. First long roadtrip, and first time hiking so any advice is appreciated. We will be sleeping in the car, and we will be cooking most of our meals. Is this possible in under 3 weeks? I would love to go to glacier national park, but I know it’s out of the way and I don’t wanna have to jam pack everything and get burnt out. I was thinking about 2-3 days at each national park and 1 day at Seattle. All of the photos are a rough idea of what I was thinking and we absolutely don’t need to hit everything on the list. In what order would this be the best? Anything I should shave off? Anything we need to see in Washington or on the way?
