Yeah call the facilities. Advocate for yourself. Don't feel like you're going behind your reps back or anything.
Call the facility you want to go to first. Say you are waiting for an FOL to ZLA, but you want to go there instead. Butter 'em up a bit. Once they say "I'll see what I can do" or whatever they say, put a little pressure on. Ask "Are you going to contact ZLA to arrange the transfer, or should I call them and have them arrange it?" Talk about it like it's a done deal. Let them know that you're not just going to be a passive waiter...but you're taking an active role in this.
If they're not receptive at SAN, call SCT, ZOA, NCT. One of them must need someone right!?
I'm not entirely sure if I talked to the ATM or Personnel at ZLA, but whoever I talked to was really nice. The front desk lady was super sweet.
