I got my glider add-on last winter, he http://www.miamigliders.com. Great people, I recommend them 100%. There was normally some lift in the afternoon, when fair weather cumulus would build.

But variety is the spice of life, and if I go again this winter, I'm just wondering if the weather in Phoenix, Tuscon or SoCal is going to be good for soaring. Any local knowledge would be appreciated!
