An encounter with this guy produced very poor quality photos, but I just had to give this guy respect for his his "craziness"! It looks as if he has a long drop tine that forks off. Anyway, I thought he was really cool.
I "tried" to focus out my passenger side window, handholding my ridulculously heavy 300mm f2.8 with 2x attached and failed miserably. I usually have my homemade "seatpod" for these situations, but it was in my trunk. My bad! I added a filter application to try to hide the poor quality.
