Sure they do. Premium is as close as your local race track, pump that sells race gas, or, if you're not using it on-road, your local airport.
Careful. Aviation gas is still leaded. In fact, 100LL (100 octane "low lead", the stuff that's dyed blue) has about four times the amount of lead that used to be in leaded auto gas! It should be okay if you don't have a catalytic converter, although some engines may experience plug fouling due to the high lead content. You won't like what it costs, though!
Some airplanes have STCs that allow them to be run on unleaded auto gas, so it's possible some airports have started selling that as well. I haven't seen it myself, though.
