So found a great hunting spot. If you sit there in a boat on Silver Lake, Peggie’s will go by in boats in the bottom left and middle red circles sections (see pic). The upper most red circles section where my waypoint marker is also set, has a spawn spot for 2 Peggie’s. It resets every couple minutes and my location is about 165 off-shore. 10 minutes and done.
Hope that helps!
