I usually ride morning/mid-day on Mondays and Tuesdays (screwy days off, I know) and can sometimes fit in a Sunday (not usually though). Red Rock, Potosi, Valley of Fire/North Shore Road, Goodsprings/Sandy Valley, Mt. Charleston (summertime) are all favorite choices for short day trips. I'm a twisty rider kind of guy.
The Spring Mountain Motorsports Ranch in Pahrump is my favorite track day hangout. I usually go with the
SoCaltrackdays events. For $195.00 you can ride all day. No groups.
Any Vegas riders wanna run sometime?
