I'm already the hell out of Dodge, I think I could stay put.
But if I did my backpack is already filled in the upstairs of my garage, i'd just include some food and water, grab my CZ-97, Enfield no4 Mk1, ammo for both already in a grab bag, throw a mountain bike in the bed of my old J10 Jeep and go.
When I was between the USAF and Army in 1969, I stayed in the woods by myself once for almost 3 weeks, so backwoods survival isn't anything new to me.
