I've been playing around with this since the day it was taken. The original color version was converted to b&w. Then I went back today and used the cross processing tutorials links that have been put in this thread. It seemed to work well with this photo. Thanks to bvy and sharlrath for the cross-processing tutorial links.
What a great character to shoot! He probably doesn't mind, either. If you know of folks like this you can see over and over again, it's a nice idea to print a small shot (4x6 or so) and take it with you to give to them next time you see them.
