I tried the phone call thing, and some did, some didn�t. I would have guys showing up at anytime, including the ones who sometimes called. I asked the guys to catch and release, and I thought that was working till I came home early from work one day and the one guy I �trusted� had 2 stringers of fish, so I bought a 60$ linksys motion activated camera. It has a very bright light you can see from a long way. I mentioned this to a couple locals and told everyone the situation was out of control, and I didn�t want anyone fishing without me anymore. I started this last fall and the fishing has been great. Where I am, the Shenandoah valley, these guys pushed hard to hunt and fish. The camera thing is worth looking into. There are allot of cheap options out there. And it really did work for me.
