I was there last week It was too damn hot and I didnt have access to a car so I didnt get much herping in. But I did manage to bike a few miles away found some good looking habitat on the side of the road and went exploring with my camera with in 10 min of looking around three navy police cars pulled up and I was questioned for about ten min on what I was doing, turns out I was too close to the Navy base lol. So watch out for that, and that habitat looks so good too.
Also hit up the dunes near sandbridge there is alot of six-lined racerunners on them that are fun to chase around!
We've gotten too close too before, but never stopped and questioned. A friend of mine though, had 2 suited men approach her in the middle of the woods once, just hiking. I think she was too close to camp david. It always makes me nervous up in western md!
