Pilot comments
This is a great site for beginning through advanced pilots. The easy 4x4 road is a short turn around for multiple flights. It's great for students in the morning with great XC potential the rest of the day. Evening glass-offs can happen - enjoy a great sunset flight when they do! Things to watch out for: North winds can be tricky here -be careful! This site differs from all the rest of the sites in the White Mountains in that it is best to launch at the beginning of the cycle to insure getting up! Don't play close to the hill!
