My partner and I are doing a fairly major road trip this summer: Brooklyn to Portland, Oregon (by way of Ontario), down the coast highway to San Francisco, and then back.
We're mostly camping (partly because I enjoy camping, and partly because it's just so much cheaper). I had orignally wanted to be casual about reservations, except for the places where we knew for sure we wanted to stay; however, because our dates on the front end of the trip are not very flexible, I realized we'd be trying to find camping the week of July 4th.
So, here's the main question: is it foolish to wait to make reservations at a campground the nights of July 2nd (we're aiming to be near Parry Sound, Ontario), July 3rd (somewhere near Sault Ste Marie), and July 4th (near Rhinelander, WI). Honestly, we're just looking for somewhere to put up our tent, have some dinner, sleep, eat breakfast, and be on our way. As of this weekend (June 17) most of the state parks in the areas we're planning to drive through still had good availability, but I don't know how long that will last.
I want the option of being flexible about where we stop for the evenings, so that if we see something really cool, we can linger, or if we are really enjoying driving, we can keep going. This worked well on our last long road trip (Brooklyn to Orlando and back), but that one was off-season, so the campgrounds weren't crowded at all.
