The nine lines into Whitpain are probably 6 in, 3 out, then, because three of those lines lead north roughly following the turnpike. Two head south... oh hell, here's what it looks like in Google Earth already; my notes in light blue. Sorry for everyone else still reading the thread.
The road with the red line on it is N. Wales Rd. The blue double line is the Pennsylvania turnpike.
It's kinda fun tracing these things out with Google Earth. G.E. looks a little better than the above image, which is compressed JPG for the purpose of showing here.
