Check robbery stats. Which banking facilities have been hit the most over the last five years, and which the fewest - and find out whether those institutions post or not.

There's a large local credit union in El Paso that gets hit by robbers on a regular basis. They post. Maybe not enforceable 30.06 posting, but it's clear that firearms are unwelcome there. There's also a large (nation-wide) bank here that has been hit maybe once that I know of in the last couple years or so. They don't post at all.

IMO, a higher likelyhood of getting robbed also implies a greater chance (i.e. liability) of employees and/or customers being grabbed as hostages if something goes south....
