One thing I never got from my searching on this... are the Global Entry "Enrollment Locations" listed on the GOES web site the only places where you can schedule your Global Entry interview? I'm thinking of signing up for this program, but I'm wondering if the only way to do an interview is to schedule it while in transit through one of those airports. I live in Austin, TX, so not in a place where I can just drive over on a break from work to be interviewed unless there are locations other than the "enrollment locations" listed.

Having to schedule an interview, which means scheduling in some extra slack time while in transit through one of those airports on one of my trips seems to me to be the hardest part of this process.
