Thanks! I just wish the outcome of the Columbia had been different.
A gift certificate would be fine. What I would ultimately like to do with the gift certificate is donate it to a school astronomy club or some similar organization so that maybe some kid will get interested in astronomy or science. I do a lot of astronomy outreach on my own to schools; it's a personal passion in that the state of science education in our schools today is dismal, and I want to give back a little of what I've been very fortunate to get in my own technical career.
I also don't want to personally benefit from the Columbia tragedy; helping some school kids learn astronomy would be a good way to honor their memory.
If you want to mail the certificate just send it to me at my address below:
Thanks again...you guys are a great resource for us amateur astronomers!...Ron
