Yeah, another good spot in SB was what used to be called Las Positas Park, near what used to be Wilcox property. It was super popular for a while with slopers, and then the park just decided one day it wasn't going to allow us anymore, without any good reason that I ever heard.
A bummer because it was a really fun combined slope/thermal lift you could get there, depending on the day, plus really easy landing until they planted all the trees on the hillside.
I was flying there when all the combat foamies got popular, and Richter was there developing the Weasel and Alula, I got one of the first Weasel prototypes. It was super fun to ballast up with tons of lead and see how many vertical rolls you could get. I may have reinforced the wing for that, I forget. Good times.
