no park and play in the immediate area. the vail feature sucks due to a very short window, but if you catch it on the handfull of ideal flow days, it can be fun. the feature in dowd below tysons seems to be gone this year, the rocks must have moved as stated by someone else. betty's hole near the botanical gardens footbridge could be park and walk and play, but it is questionable quality and a long walk to boot.
best feature is about 45 miles west, 3 miles downstream of GWS on the colorado - south canyon. otherwise, 2 hours to BV/salida or golden, take your pick.
for the most part, west slope = river runnin. sad but true. the town of avon has talked about spending $800k on features near BOB bridge, but no rocks have moved yet. vail wants to fix up their feature, but sounds like a somewhat goofy idea (air bladder dams?). GWS, frisco, carbondale are all talking about building something, but they seem to be in the early stages of planning. catch on the fly is the way of the west. later.
