D_Rob, I'm very sorry for your loss, but you accept a certain risk when you decide to fly VFR in a known busy corridor, and especially in a corridor where you know other people are going to be doing a lot of things other than keeping up a good scan. I've flown that corridor.
I agree that the "right side of the road" rules make sense (and a lot of people will still never read them because they won't have the TAC or will ignore them to get that great view...), but I don't agree with the closing the East River to VFR traffic unless LGA tower clears you part. If you've ever flown GA around the NY Class B you'll know why. NY TRACON never allows you to transition the Class B due to workload. They might as well just say 'East River closed" because there is no way that LGA tower is going to assume the extra load of Joe Shit the Rag Man and his other GA buddies taking a joyride up the river.
