I saw some horseshoe crabs around thompson beach road, but I think they were dead. I intended to go to some beach areas, but lots of people were fishing, and I know how I dislike it when people walk and hang around me when I'm relaxing. I also intended to walk out to the bay via a murky old road, but a storm was brewing and high tide was coming. That area down there is my favorite spot in nj, the wildlife and diversity is unreal.
When the horseshoes come in mass, that is when i hang up the surf fishing poles for stripers in fortescue, the gulls are all around going after the eggs, i actually snagged a couple of gulls casting over the years with the line, no hooks thank goodness, releasing them of course, had to put a burlap bag over their heads, they can get quite nasty.
I also had a creep at fortescue complain to me about getting the horseshoes off the beach at lowtide and putting them back into the water, unbelievable, he said let them die, well they went back into the water, all the time as he was cursing me out, he did not realize catching a striper at the time with all the crabs in the water was nearly impossible, time to pack it in and go home.
