I don't know if I have cell signal there or not I have never looked. Good chance I wouldn't as this was on the 3rd floor and there are 9 levels to this garage.
I can't make out the bottom two lines either, I think it was just the Baylor All Saint's stuff, or maybe sorry for any inconvience.
I definently watch out more when I am in parking garages, and this could certainly be a part of somebody's plan of attack. Some BGs put a lot more planning into their attacks than some give them credit. Just like gun free zones, nobodys wants to admit that the BG targeted them because he knew no one could shoot back.
The real kicker is that all of Baylor's building are 30.06 posted.

So my firearm gets left in the car, as I would not drive around that part of town with out one.
They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.
