Last year Kansas Wildlife and Parks (or core of engineers, not sure which one) shut down the Outlet Area at Clinton Lake state park because they were sick of the violations, good for them. I am not sure how long it was shut down, but I believe it was more than a few weeks.
I am to the point that I say things to people all the time now at my local fishing lake (Leavenworth State Fishing Lake, aka "Tongi Lake"). I am just sick of the littering, stupidity, and poaching.
