During sturgis week keystone becomes extremely busy. Long lines of bikes everywhere. Even the week before and after sturgis

The list of things to do is still valid. Wind cave Custer 1880 train needles highway. Try a chuck wagon supper. It's touristy but enjoyable. Deadwood isn't too far away for a side trip.

I haven't been back since 2007 but still talk to friends that live and work in keystone and sounds like its stayed about the same.

I made the trek from keystone to Denver and back twice. It's a long haul not much to see.
