Colorado Springs
We stayed at Garden of the Gods RV park, last year in May. Very friendly people there. Lots of RV's crammed in the park, but the site wasn't crowded at all. We had a little trouble finding a hole in the trees for our sat dish, but that was because we got a site that backed up to a spring. The road noise was loud during the "rush" hours, because the road went to Manitou Springs which also means that G.O.G.s RV was central to all of the tourist traps. We easily went to Pike's Peak, North Pole, GOG's (do not miss this place in the evening!), ice skating museum, Cripple Creek (train ride & casinos), and Seven Falls (climb the stairs!)
