I'd figure on getting the hell out of there, preferably before shtf, but if need be, afterward. But go offroad, via a quiet model of motorcycle, and go at night. So it takes you all night to cover 150 miles safely, using active IR goggles, so what? Everyone has eyes and is out and about in daylight. A guy, moving 10-20mph(depending upon terrrain) is an almost impossible target, beyond 200 yds in daylight, beyond buckshot range at night. You'd be much better off, some place with trees and water.
