If I'm on a spot and someone gets to close I'll sit tight and act like I'm detangling a bird nest or go take a swallow of water to kill some time so they'll go around me and not know I'm on something. The birdnest thing works especially good on points because no one will cast close to you. Whatever you do don't use marker buoys if there's a lot of boats around. I don't feel bad for KVD either, that's part of the price of fame.
