a little OT, but it is amazing the people who show up to disasters. when i did katrina, there was a man and his wife working in the staff shelter. to this day, i don't know who he was, but apparently he was quite wealthy. he and his wife were mopping floors and cleaning toilets. one day we had a bunch of fantastic food show up. turned out that he didn't think we were eating healthy so he had a bunch of salads and other stuff brought in and he and his wife spent the day preparing some good food for all of us who had been out in the field.
had another one when i was in Iowa. was running a kitchen operation and the HQ manager took me aside to ask me if i minded taking a guy with no training, but who really wanted to work. it was odd, but i didn't care. another pair of hands. turned out he wanted to get out and see the disaster so that he knew best how to direct his big donations....which usually included things like rebuilding school...but he didn't want anyone to know who he was.
never found out who he was either :-)
there are a lot of quietly generous people out there and you never know when you are working with one!
