No kidding, that pic is of a pretty light day in fair weather. Im surprised to see the peds behaving in such an orderly fashion -- must be a big tour group with them all going the same direction. It's when it's crowded and peds are walking in both directions that things get dicey, IME.
Me? After nearly getting knocked down by a jogger once I've given up on going anything other than slowly across the BB. I've accepted that if the weather is good, it's going to take forever. I save my ire for Chambers Street, for which I harbor a special distaste. It's an awful to cross the island to the Hudson Greenway along Chambers. A propos, anybody have a better route? Also, I tend to save the poorer part of my vocabulary for peds in the bike lane in Central Park, especially from what, the 7th (or is it 6th?) Ave entrance up to 72nd where cars are allowed all day. They drives me nuts!
