damn, man, i grew up in Perkiomenville and went to school in Boyertown. That Pottstown/Reading/Allentown triangle seems nice (i'll likely never have my bike up there anymore now that i moved to NC, but).
SE PA has some of the best roads, because a lot of them were wagon tracks/cowpaths/whatever before the days of blasting straighter roads, that just have So. Many. Curves. NC piedmont doesn't because it's flattish... you have to follow a creek to get turns
It sucks now because i haven't been on a motorbike in 10 yrs and i'm frankly timid, but when I took a friend who grew up in Houston and Atlanta home (en route to Canada for a scooter rally) he was like "oh, no wonder how come you can find apexes, this is how you go to the grocery store?!"
i think i oughta set a goal of riding up there from NC and going riding around with you guys.
