" I certainly would never set anchor and fish in front of anyone else's campsite. I at least hope I'm not in the minority with that. " -DB

I think you may be, at least in the B-dub, where the campsites in some places are on top of each other.  Can't recall how many times I've had canoes just drift past the shoreline in front of my camp while I'm having dinner or just relaxing for the evening. Not even an "oops, we're sorry, we'll fish the other shoreline".  Makes you want to fire a shot across their bow.
