I hear a lot about the "Dumping Grounds", where is that exactly...I keep my boat at MetroPark Marina in Gilbralter. Unfortunately my boat is not set up to troll so I mostly drift with bouncers and harness. Any other good spots to drift? This is only my second year of fishing for walleye and I love it but have only limited out about 4 times those 2 years.

Thanks for any help.
