One of my favorite destinations is Cody Wyoming. The town itself is
charming but it's proximity to Yellowstone, The Beartooth Highway, The
Buffalo Bill Dam and several other attractions make it worthwhile
spending a week or more, there. All of the nearby campgrounds were
cramped and booked solid. Nicer spots could be found near and in
Yellowstone, but most had no sewer and some had no water or electric.

How far in advance should reservations be attempted at those nearby
campgrounds...any idea?
