Here is a brief excerpt.
“Believe it or not, slope soaring is entirely possible here in sunny Florida, despite the fact that within 30 miles of the coast the ground rarely gets more than fifty feet above sea level. While our thermals in the summertime have been known to lift small houses off their foundations, the cooling seabreezes that form much of the year are a convenient source of lift along our beaches. Slope soaring is not difficult for anyone who is capable of flying a model sailplane safely. It also offers some unique qualities and opportunities not found in thermal flying. This section will cover a beach environment like we have in Florida, but applies also to any slope with a bit of flat area in front… hills, mountains, large flat-sided buildings, highway overpasses, etc.”
