So this is a favorite new place for us in Longmont, CO at Rocky Mountain Elementary School. The program involves swinging, crawling and climbing on, over and through ropes and other obstacles. Rope World helps children develop self-confidence, agility and strength as they play freely in a supervised environment. We found out about it through a mom's group. Rope World is part of this school's physical education program and they open it to the public for two week sessions a couple times of year. We went once last week and then again today. Weston really enjoys and I hope each time we go he'll try something new. If you live in the area I highly recommend you try it (well worth the $4).
