Syringe Fan?

These shots are from the 2009 Tour of California and I found myself confused by several aspects of the photos. What was this fan thinking? Was he pissed at Pro cycling and the fallout from the drug scandals? Did the fan think he was being funny and how did other fans perceive his presence on the side of the road. I think I would have found myself giving this tool some grief. Anyway, it's sad to see and know it's out there. I'm glad he ended up in the snowbank.
