Well it depends on the group. I have three that meet in different locations and times.
My primary location has stone steps, so we can't wreck those. The door is, on the other hand, very close to the wall and quite braceable, with a 1.5 story drop as an escape route. If we aimed for the bush and rolled we'd be able to come up from the fall running. No food or supples to speak of. Depending on the zombie type we might be able to hit the lake and wait things out on the small island. Otherwise we'd rush the fence, use the side gate, lock it behind us, and make a break for an enforceable holding position. Not alot of those, so we might hit the Safeway up the block, grab supplies, and get the closest transport possible to get away from dense population centers. There's a pair of big pawn shops a little farther beyond, we could get non-food items and many some weapons. After that it'd be think and run.
The secondary group/location has wood stairs, so we'd be able to sever the connection to the horde. The drop has no hedge and is higher but the location is more secure so we'd try to just wait it out.
