That's good to hear. At first, when I saw the thread name, I thought the worst, that he had been killed in the WTC. I knew he didn't work there, but still I was obviously relieved to see that the story was that he was helping with the rescue effort.
It's not surprising. On a much less dramatic level, he helped me (basically a complete stranger to him) out through this board last spring. I had ACL surgery and was asking on the board about Cyrocuffs (a piece of medical equipment that you have to buy following surgery). He offered to loan me the one he used for his surgery a few years back and save me about $125. It worked great and I mailed it back to him recently (Tog, if you're reading this, I'm assuming you received it OK.)
Anyway, I thought that was an interesting anecdote showing on a small scale, the kind of heart he has for helping others.
May God bless and comfort all of those touched by this tragedy.
