Pilot comments
This launch site was used for a US National PG competition. This launch is great for all levels of pilots. Many launches to choose from. The only drawback it that the landing area is a long glide out. So don't think about landing! Just fly XC. Its easy to get stuck deep in the mountains. Be prepared to land out on a ridge if you hang out too long! Wait for a lull to launch!
