Sunday, September 8, 2013, Nissan Fontana Dealership (which is in Fontana, not Laguna ;-)). It's a big officially-organized annual meet. Tons of Zs and GT-Rs go, among other Nissans. Great place to do some R&D on parts because everyone's modified in some way. This year its happening in conjunction with a SpeedVentures track day at the Auto Club Speedway. I will be going to the meet at the dealership, I won't be doing the track day. My wife will come if she can get the day off, so we might go eat at a nice outdoor shopping area nearby and look around before cruising back to LV late afternoon.
The Vegas group usually meets early - around 5:30-6am, if I recall correctly, at South Point and cruise out from there. One stop for coffee on the way, and it's a nice chill drive.
Here's the event on FB.
