A small kidney shaped pool in Mepel cambridgeshire where I caught my first twenty in 1983. It held about ten carp between 9-21lbs, most lovely dark scaley mirrors with a few commons. I spent a lot of time riding my old Honda 50 moped the 40 mile round trip just to spend days there trying to tempt them on floater cake and luncheon meat.
I learned a lot as you do when your young and it's a place I have very fond memories of.
