My Logo (in the lower right hand corner of each page) is a profile of me that was taken on my trip to San Antonio, TX.
(The photos from the trip can be seen here.)

My brother and I were sitting on the train at Six Flags, Fiesta Texas with nothing to do, so I told my brother to pose for a couple of pictures and I started snapping pictures.  Then he began snapping pictures of me.  The picture I have chosen to use as my logo is my favorite pose.
