We had a free day in Boulder and lucky us we were able to call and get 3 flights for the same day. I am pretty sure that was pure luck. This operation is awesome! I took my 6 year old and my husband took our 4 year old. Our nanny went by herself. Our kids are both dare Devils, adrenaline junkies so this is NOT for every youngster. Use your best judgement. You know your kid. The guy that runs it didn't think our kids would handle it but they did. I trusted my gut and boy did they have an amazing time with Ty. What a great guy. He made sure they were safe and happy. We all had great flights. He is such a nice guy. I trusted my life and my kid's life with him and I would do it again. Hope to be back next year! Thanks for the great rides!! It was spectacular!
