Note: Flickr recently went through a massive server transition, and portions of the service are still being worked on. Among the problems is that mosaic thumbnails on Collections are not visible, which means my primary page here for showing groupings by year are missing those thumbnails. The links do work—only the thumbnails are missing, so you can still navigate into a year to view those photos.
Some former coworker friends of mine also took a vacation to Las Vegas. Their trip was in mid-November 2003. Later, when I found out about it, Leonard and I had a look at each other's photos, commenting on shots the other person didn't get during their trip. He took far more photos than I did (more than 500 total), although many of his were shots that included his family. With his permission, I picked out 30 of my favorites to share here.
