The women's FCI in Dublin, California is an easy drive and they (presumably) have her level of security. If she wants to say F California (maybe she did in her PSR) then maybe Bryan TX is her destination. Could also be some random third facility. I don't think if a flight risk to Mexico is a concern that they'd be sending her so close to Mexico, but it may upgrade her security level enough that Dublin's off the table.
It's all time and it all sucks. Her kids will get to see her if their father wants them to, perhaps every weekend.
