I want to give this a shot; our club has a few guys that go slope soaring just a couple miles from where I work, down at the beach in Carlsbad. Only problem is that weather has been so lousy lately - cold, overcast, and what we call "May Gray/June Gloom" here in San Diego, along the coast.
I've not done it, but I've picked up the thermals at our field with powered planes, so I know how to ride the lift; I've also practiced a bit with sims. Only problems I have with the concept of slope soaring are the launch (I suck at hand launches) and the landing, because where I'd have to land at our soaring site is really either a narrow spot along a popular walking trail or on the far side of the coastal road, where cars usually park. I'll figure it out eventually, but I want to watch some of the other guys do it first so I have an idea.
