I thought we headed out the back door? As in escape routes and safety zones. I'm sure we barricaded the entrance door but the back door was probably overlooked because of all the "panic"

Also I have my The Zombie Survival Guide with me. It points out buses are bad because of the door and all the glass. Then again given the group size we have... I doubt we have a choice. unless we wanted to split up the group. 

[@ChronoBovino] The dead don't run in the walking dead. Its because of the necrotic stiffness in the undead. Something about crappy hand eye coordination and that they have never been seen jumping up or down obstacles.
