I used to work at Lock 52, and it can be quite an experiance. There are some ice pictures of 52 on the internet under
http://marionky.biz/local1373/LOCK/DAM52.HTM. Shows some pretty good pictures. Wiskers, I know what you mean about being stuck watching others fish. Had to do it at 52 and Smithland many days. Now I am stuck in a control room with monitors at 3 plants watching them catch while I am on 12hr shifts.
