Part of the 2009 Photochallenge. Today's theme was texture. This was much easier than I expected. Once you start looking for texture, you find it everyone. The trick was to get a fairly unique shot. This is one of the walls at the Montgomery Street BART Station. The light is from a stopped train, and you can see the reflection of the yellow safety strip and the trackway in the semicircles. I'll be posting more from today, but for now, this is my official entry for Day 27.
