I haven't been there for probably 12 years, but when I was growing up we used to go near the bridgeport bridge. Just south of it on the VT side there was a tunnel that went under the road, and into a huge backwash area that used to be filled to the brim with gar. I remember seeing them all the time there, and I also remember seeing a dead one washed up on the shore that was well over 3' long. Don't know what it is like now, but there was lots of them back then.
