Try to plan a summer trip with 2 adults + 9 yr boy.
Fly to Denver then rent a car.
Only has been Keystone 4 yr ago once during Spring Break.
Would love to see the summer scenery.
Would local experts suggests some:
1. if we stay Vail a few days, Aspen a few days, what other day trip we could make?
2. any place we shouldn't miss?
3. what the good activities? Is there anything like Monkido (www.wildplay.com/elements/monkido#access)? My 9 yr boy loved it when we visited Whistler 2 yr ago.
