There are a ton of users in the LA area. My suggestion would be to go to the JAMF User group meeting in LA (it was at the Roosevelt Hotel in Hollywood one year.) Another thing I suggest is to check out other vendor meets. A few years ago I went to an Adobe conference at Paramount Studios and ended up meeting 5 new JAMF admins.
I'm going to be in the LA are for a couple weeks for work August 18 - 28(ish) and would love to grab beers with some of the other admins in the area. Figured if I posted now... there should be enough time to plan.
I made a meetup group. Feel free to join. I'll post details in both places.
