Sebastian has one in Evansburg State Park in Collegeville. I see it listed as 7/24/2011 in the Horse of the DE Valley's online calendar. (You need to click on June but it will then scroll through to July). It is normally a ride that involves questions with points. Not quite a true paper chase for optimum time but still fun.
I haven't been to either of these but might try the Amwell Valley one.

Oh, well, clearly you're not thoroughly indoctrinated to COTH yet, because finger pointing and drawing conclusions are the cornerstones of this great online community. (Tidy Rabbit)
