I'm glad you made this posting. I was hoing to do it just now, but see you did it first.
The strange thing about this cache is that there is lots of controversy about it, but there are only two DNF's .. one of them being my own. I walked that bridge for 20 minutes. I went back later and tried again. There is only pne place where I think it may be, and if it is, it's not a 2/1 as he has posted. I think the 'Rock" may mean the pebbles UNDER the bridge and the 'Roll' may be the mechanism that pulls this bridge into the open position. This is all about 5 feet under the roadway. I looked for the 'ladder' but if it's there, it's in a place where I wouldn't want to be. I am sure it is very illegal to be down under the bridge. The areas around the bridge are fenced off. Fences mean...Stay out!. This is supposed to be a family sport and no one is supposed to get hurt or arrested finding a cache.
Location on this bridge (about 100 feet long) I could almost see, but I could not see putting it on say the QueensBorough Bridge. There is Stage 1 of a multi on the Brooklyn Bridge, but you just have to copy down info from a sign. I think that is a good alternative to actual bridge placements. Lets face it, to do geocaching, you do look 'suspicious' especially in city settings. I got a request to move a cache near the Arthur Ashe stadium in Queens because although it was on the outside of an ivy covered fence, I was still too close for comfort for the terrorist wary police. This is one reason I do not support GC.com's ban on Virtuals. You lose some very interesting sites, without compromising security.
Yes, magnetics on phone booths or on the backs of Coke machines are on the 'edge' of legality...but they are within public reach. If a cache is hidden BELOW a bridge in the mechanism's of that bridge, it's a different story. If you follow the "But it's ina telephone booth" argument, why not place it inside the telephone exchange building and sneak in the back door?
I've reported 2 caches so far as being in problem locations. I was 'upheld' on one (a cacher who is no longer active had one placed in Manhattan where the only access was up a rickity staircase 4 blocks away, behind a fence that said "No Tresspassing". The other was a lamp hide in a parking lot in Michigan where it said "Parking for Ford Employee's only" on the grounds of their assembly plant. That one it said, is generally kn own to be an 'open' lot and 'everyone' knew that you could drikve in their even if you were not a Ford employee. But I don't live in Michigan and I didn't know that. I still think the decisoon was wrong, but hey, I don't write the rules.
Admins keep their identity secret. I suppose with good reason. I've been told I know NY Admin...but I have no idea who it is. I also know OReviewer--as many of you do. (look at the name and you'll know right away) Ben makes no secret of the fact that he is a reviewer and openly discusses rules and problems with people. I think the transparency is good.
I've had my say. Now let's go out and have SOMEBODY find that Rock and Roll and Union Street bridge caches. And let's find out if it is in a legal or illegal spot.
