Thanks for the feedback.
I was at a wildlife management area near Winslow, NJ. I think it's actually called the Winslow WMA. The forest there is not 100% Pine Barrens - there are fields for attracting deer and the forest is probably more oak than pine. I have had poor luck in the deeper Pine Barrens, though I've only gone out a few times.
You mentioned that you are only taking pictures, which is a good thing, because New Jersey is very tight about collection rules.
On the date I found that racer I found 3 worm snakes. Now the funny thing is that I went back twice over the next month (found a large black ratsnake, nesting painted turtle, more toads, green frogs) and on both trips I found a worm snake under one of the same pieces of debris I had found one under on the first trip. Same one? I don't know, but it was strange to the point of spookiness.
See the posts for June 26, July 3, and July 10 at the website below for more on those trips.
Cheers,
Billy
