I'm going to have to ask where in houston, because it seems there is a meet in every section of houston because people are unwilling to travel more than 10 minutes. Also, it depends on what you mean by "meet". Do you mean stand around in a parking lot or going to a bar/restaurant and talk about anything but subarus?
There's the HHH which has been going on for 10+ years.
