"pepper's house" has readily available gas and a way to pressurise it? That's new to me. :P Also, scuba supply store also destroyed...wouldn't find anything there either. Well, maybe a little bit. As I said, the idea is that such things are very scarce and valuable.

As for gas powered saws, yes a lot more fun. But once again the gas problem. :P Though you could find a few intact cars here and there to power it for a while.
