745 Shell Island 4500 ft. AGL Good flight. Climbed to 4500 ft. AGL trying to get above the marine layer. The air was smooth with a 25 mph breeze from the SSE. Thermal layer was obvious at 100 feet and again at 2000 ft. Share this:TwitterFacebookLike this:Like Loading... Author: JoeO Powered Paraglider pilot since 2005 View all posts by JoeO
