Welcome to Vegas. Hope you are enjoying the 115 degree heat. Don't worry though, it doesn't really get hot until August!
As far as Mustang clubs, the Mustang Club of Las Vegas is the only all mustang club I know of in the city. We meet the first Wednesday of the month at Desert Pontiac. (Don't ask) at 7pm. Next one will be Aug 7. If you have any questions you can call Bill Neely @ 434-3250. He is the club president and a good guy. The club is pretty active however, there is a power struggle going on much like what is happening with the MCA. Not much will be happening until September when it cools down some. If there is anything I can help you with, P/M or E-mail.
