Instead of getting mad and fighting, be better than that and outsmart them. I'm sure you were probably fishing the Sky, Old Chum, as I have been fishing the Ol' Sky for over 15 of my 26 years and I have never seen it so bad as it has been since it opened June 1. If somebody corks me when I'm on anchor, then I just grab one of my float rods and let my float freespool right down next to their boat. The corkers will not know that your float is right next to them until you give it a water-slicing yank and it's guaranteed to startle them which usually is enough to get the message across. Parker, Drift Boat(Mac), and I were on the Snoqualamie last winter when some guys decided to drop anchor right in the middle of where we were swinging our drift gear. I pulled the old yank the float trick right next to their boat which scared them and they pulled anchor and we had our hole back. Just my .02 on how you can get your point across without gettig violent. Peace
