What are useful/fun/collaborative things that can be done with a PDA, computer and a small GPS device these days?

Say there's another huge blackout like the Northeast had a few years ago, and let's say it lasts two months... Will a GPS unit in my dashboard and powered by my car still be able to connect to the satellites it needs to, to direct me on my way?

Does anyone know what this facility is (google satellite image, Action, California.) It looks like a nursery, or something similar, but I'm trying to get more specifics for a hiking guide I'm working on (without taking the long, long drive out there.)

How can we find the photograph DATES of the satellite images in Google Earth? [more inside]
