Here we see some secret service snipers and spotters. These guys were visibile to everyone. At one point though a hidden sniper came out of a roof top to my right and pointed his rifle in my general direction. As soon as I saw him he walked back away on the rooftop. Maybe I look scary with my zoom lens. This is the Obama rally in Denver on 10/226/2008. I believe there were over 100,000 people there.
