Cabinfever-
I for one appreciate the situation that you are in. It certainly does not help when there are a few out there who cannot bring themselves to show a little respect for you, the new owners of this property. I for one respect your request and if I do decide to drop anchor in the area I will be more than happy to keep a respectable distance.
It truely is unfortunate to read some of the responses to your original posting

. I don't think what you are asking for is unreasonable whatsoever, and for all you nay sayers out there how would you feel if the situation was reversed... and this was YOUR problem

?
Enjoy your new piece of the lake.
