SCUBA club in college used to cut a large hole at night in the local hot spot and cover with a large tent. Next day when others came to fish they would dive and grab lures with a pliers. Most often, the “fish” got away or broke the line. Occationally, however, when a pole was seen unattended, the entire cheap pole went down the hole! Funny to watch the reactions and retelling of the “big one that got away”.
