Note Per Rayman's find log of 8/20/11, the camera pictures on the web appear to be about 5 minutes behind real time!!
This webcam is in downtown Lockport, N.Y. mounted on the roof of the Lockport Municipal building. It rotates approximately 180 degrees, and updates on the web every 15 seconds. You will be standing at the far Southern end of the webcam's rotation. You can't miss the spot, there is a classic Blue and Yellow New York State historical marker there. This is not the greatest webcam I've seen for making a webcam cache, but I have seen worse. Additionally, the captured picture looks quite a bit better once saved to a computer than the live webcam view on the website. The webcam was actually acting up the day I was there and snapped the coordinates, so there is no picture of Mr. Yuck, and you'll have to stand as indicated by the red arrow.
The URL for this webcam is http://www.elockport.com/webcam-lockport-locks.php Now if you are doing this webcam cache the "old-fashioned way", with a remote helper sitting on a computer, they need to right click the picture on the website once you appear in it. It will name itself "3Rz.jpg" by default, and they need to save it, and you just need to upload that picture with your log to claim a find. Doing the webcam cache solo the "newfangled smartphone way"? Well, you're on your own then. Models and mobile web browsers vary greatly.
As I said before, not the greatest webcam, but I think it will work. As long as there is a discernable human figure standing there looking towards the camera, you'll be fine. Feel free to hold up your GPS, or flap your arms if you like. Oh, and of course if you look down over the railing in the picture above, you will see Lock #35 on the New York State Barge Canal, AKA The Erie Canal. Locks 34 and 35 raise or lower boats approximately 50 feet at the Niagara Escarpment.
