I know there were lots of people looking for rides here and there..thru hikers, people needing to pick up rental cars at the InyoKern airport and such. There's one opportunity. And lots of people visiting National Parks..from all over the world. Prolly not too lucrative, but then again, might supplement the bank roll and be able to hike while you're riding the unemployment train. Kinda late in the season now, though...how about "Fall Foliage guided trips"? Not too late for that :-)
Looking at the big picture: might consider some Ultra light backpack ideas you can patent and maybe farm out. I have a friend who is designing light-weight, 1-2 person "overnighters" trailers that you can haul with your average car. Tough times call for innovative thinking. Not to make light of the situation by any means. The company I work for just had it's second major Reduction in Force (they like to call it "RIF"!), this year, and much more is planned.
