[wedding photo of Greg by Dan Warsinger]

This photograph is copyright © 1993 Dan Warsinger. Dan was an amazingly studly photographer, both technically and professionally; he was also a really nice guy. Highly recommended for anyone getting hitched in the Yosemite area. And no, Greg is not Weird Al.
