Let's see. My PSK would cover me until I got to the nearest strip mall, which are usually situated about 1000' from each other around here. As long as I have some cash, I could ply myself with McDonald's, Taco Bell, pizza and Chinese food while waiting for a cab to take me home. Of course, take me out of my normal stomping grounds, and it's a different story. I better go practice my trap-making skills...
