The Red Cross is what I would recommend. They have a large Disaster Services Technology group that gets sent out to help set up communications equipment in disaster areas and they have the Emergency Communications Response Vehicle. http://en.wikipedia.org/wiki/ECRV/ Which is a pretty nifty truck to play around with. Though there are only 12 active right now so you have to live in or near a city that hosts one.
