I wasn't even on the trail at that point. It was a commercial photo walk person with about twelve people, who either thought he owned the Park or had exclusive rights to that spot. They were the ones clogging the trail per se. Once I had one of those jerks on NG contract simply dump his class on me so he could go do his own thing. He told them to follow me and shoot whatever I did. Didn't matter and I politely ignored them (they weren't the jerk charging tour money). I took a few shots with the Sinar while they blasted away with their motor-winders. Not one of them had any idea what I was actually looking at, or why I had the tripod set up exactly in that spot. Of course, I've run into serious photo clinics by very conscientious names too. But I mostly avoid known scenic attractions completely because I prefer to photograph in peace.
