Absolutely. This spot:
...is the main spot at SAN
, where the vast majority of A.net shots are from. It's a small parking lot (5 or 6 spots) right where Laurel and Harbor meet/fork. Often limos and hired cars wait there. You can park there, and climb on the green electrical box which is about 4.5-5 feet high and stand on there to clear the fence. I've been there dozens of times and stood up on that box in full view of civilians and cops and have never been harassed.
The best part? It's a stone's throw from the terminals when you arrive, about a 90-second drive, though you may have to turn around at the next light because you can't really enter the lot heading east, you have to go west.
BTW, what's your planned itinerary? You're a few months early for our non-stop on BA
