I wouldn't be able to get out in that time. Traffic would build too quick, everyone would be going bonkers and possibly joining in. I can't get out on foot in that time and there's no other transport available. Oh, I'd try, but I'd probably get shot or run over in no time.
I'd probably run up the main road. There's far more room and when I get out there's a lot of trees and fields between the buildings. If I felt confident, I could go up the road and go into the villages or hide under one of the bridges as nothing could really get down there or break the bridge. But still, half an hour? Pushing it.
Alternatively, get into town. Plenty of secure areas, but its like the eye of the storm.
