I still don't know why I only get an empty box with a blue "x" in it when I try to post a picture now. Anyway, this should be pretty simple. If you look closely at the first picture it gives it away. But this spot is just off the intersection of a highway whose digits add to 4 and another whose digits add to 13. The large rock behind my bike is a big hint. I think this place is the only park of its kind in MS, but I'm not positive about that! It's all paved roads except gravel the last 50-75 yards or so. I have another picture I can post if needed, but that's pretty doubtful.
Best I could do in what little time I had after work. Otherwise I'd have made you guys wait till the weekend, and we've gotta keep the ball rolling! Have fun and good luck!
