Johnny, I share your frustration.  From what I understand, to get on the beaches that you mentioned, you have to know someone who lives in the community, who is willing to let you park in their driveway.  Otherwise, your car will be quickly towed.  Of course, there is always the possibility of using a kayak or canoe to access these areas.

You shouldn't overlook the public beaches, though.  Brownies Beach can give up some amazing teeth.  Even in the summer, when the beach is so crowded that it's hard to find room to walk, much less hunt, an experienced eye can still find treasures that most of the summer searchers will miss.  Practice and persistance definitely pay off with this hobby!

Good hunting!

Johnny, I'vev been collecting along the cliffs for many years now, and like Tom said, there are only a few public access points, including Breezy Point park, Flag Ponds state park, and Calvert state park, and of course Matoaka Cottages (small fee).  Some of the private areas, all bordered by communities that will chase you out and/or have your car towed and you arrested, are places like the Willows, Plum Point, and others.  I would recommend joining one or more of the various Maryland fossil clubs (Maryland Geological Society, Calvert Marine Museum Fossil Club) to join those clubs on periodic trips to these private areas as well as some others such as Scientists Cliffs, Parkers Creek, and others.  As Tom  indicated, you can collect at any of these spots if you access them via the water by boat, this is the grweat thing about the law in MD vs. the law in VA.  As you may have read under the Maryland Fossil Hunts part of this website, some of the folks launch a boat from places like Breezy Point and then hit the less frequented spots such as Willows, Plum Point, and points south of there.  I have read on other websites about folks being able to scope out areas that are probably almost never frequented by collectors.  Makes you think that there are teeth just littering those beaches!

Have fun and keep a close eye on the rocks above!

Johnny,  Like Tom said don't give up on the public areas. My best Meg just under 4" came from Brownies Beach as well as a partial Porpoise skull out of a block of fallen clay in the water. I actually had walked past the skull on the way down the beach and didn't see it until I was on my way out. My advice is hunt smarter than the others. Slow down, look closer and then look even closer. There are many fossils that get walked past by most of the collecters because they are in too much of a hurry. There are times I am guilty of going too fast as well. Most of all have fun and be safe!
