Some type of Hobo gathering. Check out the pictures after the rambling text. Man are these people dirty. I especially love the caption "Tex rolling one". Nice DDP shirt too... BANG! I can't imagine why the cops would be harassing you with this many transients in one place.
If you go back to the root of http://www.northbankfred.com/ there is a ton of stuff with lots of other pictures of dirty hobos. I did not see Kendall in any of the photos..
