Trees, fences buildings...easy to get hung-up. The area was not clear cut before the dam was built so it can be a mess.

A bouyed line to the anchor crown can work but sometimes I am too lazy for it.
Often lift a tree nearly as long as the boat before tripping the hook loose... The things we do for relaxation...HA!
