Not that i am aware of. I got there about 5:45 and parked a couple rows back from Starbucks so i was out in the open and visible. I stayed by my car until like 6:30. That parking area was very busy though, its possible someone made a drive by and decided not to stay.
I wont deny that i am a little frustrated, its a two hour drive from here to Sacramento. Next time there is a meet ill just have to get the number of the host or something, and not try and go to one so small.
