For trip planning purposes, what resources are you using to find campgrounds? I have had great experiences at State Park campgrounds, and those are easy to find by Googling the "Louisiana State Parks" for example. The DW and I have had a condo reserved in Crested Butte CO this summer for some time, but for summer of 2018 we are going to camp our way across the country. Do you find that reservations are necessary, or can you more or less fly by the seat of your pants? I would assume that in part, that depends upon the popularity of the destination. Let's say I want to end up in Oregon, how would you go about finding and getting good info on campgrounds?
