Another of my hobbies us high power rocketry. I currently hold a level two certification from the National Association of Rocketry.
My local club is The Utah Rocket Club, and I try to fly with them whenever I can. We have a great area with a 10,000′ waiver that we use once a month. Once a year, we put on Hellfire, which is held on the Bonneville Salt Flats. The waivers generally have windows to over 25,000′. It is a great time. Contact me for more information.
