I funny thing happened today while I was watching a friend sneak up on his tip-up (I don't know why he was tip toeing up to it, and neither does he) but as he did it tripped and he landed a decent largemouth bass. Later as we were pulling our tip-ups to go home I walked toward my farthest one and as I got there it also tripped and had a largemouth on it. We were in very shallow water (2-3'). It was as though they were watching it and when they heard someone coming they decided to grab it and run, either that or they had already eaten it and were just hanging out when we scared them away?
