You are right! No time like the present...
last year, while planning a two-month trip out west, I asked for campground suggestions for Cody, Wyoming (I wanted to visit the excellent Buffalo Bill Center of the West before we headed for Yellowstone.)
Lots of folks suggested Ponderosa Campground, which I did book for three nights. It worked out perfectly because the CG is right in town, walking distance to the BB Center, which I visited for two days. Tickets for the enjoyable city trolley tour were available at the CG, and the trolley even picked us up at the CG check-in office, ending at the Irma Hotel for the late afternoon gunfight. It was a relaxing, fun visit.
So many thanks to those who took the trouble to post answers.
