Yeah, just keep a look out on here. These guys keep the forum pretty well updated on events in the area.
And to add to my post earlier. This one wasn't advertised quite as well and it was also pretty darn cold that night. The first one, it was raining but they still had a good turnout (15 Jeeps or so and about 40-50 people). I feel certain that once it gets a little more organized and the weather gets right it will be a great turnout. They have been doing live music at each one. Some food specials and better drink specials geared toward the 4x4 guys would definitely help the turnout.
