As Jayme Blaschke mentioned in his comment on my post of April 23, the membership directory is one of the most useful things you get in a SFWA membership packet.
It does come in handy; it's a great reference work.
When I flipped through my copy, I noticed Ray Bradbury was in there. So I did something I should have done 40 years ago - I wrote him a fan letter.
He was nice enough to drop me a short reply, too, and wish me luck in my career.
