Bancock - I tend to agree with you on where I fish. I simply avoid the larger lakes that allow skiing / personal water craft. There are a lot of places that these can be avoided. I do fish Spencer, but that is before Memorial Day when high speed activity is at a minimum. You can always head to moving water - not seen a jet ski on the Yak, Sno Forks, etc.
Up at Mason, we actually have a sheriff boat that will cite violators - nice to see!

All of you be safe this weekend!
