Oak Hill is having a Cruise and Blues night on the 23rd, maybe a trip to San Marcos and then Oak Hill on the way back?

Quote from Cliff Anderson of OHAN:
The Oak Hill Association of Neighborhoods is sponsoring an event, October the 23rd, to
promote Oak Hill community spirit. It will be at the old Oak Hill Elementary School (up by the Austin Pizza Garden) on that Saturday, from 1 pm to 7 pm. We will have several local bands, be booth for local civic groups, artists, and merchants.
It will be free to the public.
Besides the exhibitors, the only cars permitted to park on the site will be street rods, classics, muscle cars, and exotics for show. We will also have a couple of trophies.
