Ashboro NC is also a diabase area.

This is a difficult choice as the bouldering areas in PA are amazing. While haycock may have the most problems - it also has the most problems (not a summer area, bad landings, difficult navigation).

So I'd have to vote Ghost town over Haycock as a bouldering area - for the superior asthetics and amazing quality of the problems.

However.....

My vote for what is the best climbing area in PA and the one that people would have a reason to visit the state for - would be Hunter Rocks for the amazing rock quality and features. Perhaps the stickiest, coolest featured sandstone in the world.

And Hunters has something no other climbing area in the country has - quality Font Circuits (minus the red and blue paint). Because of the Dresden-like mini-towers and convoluted nature of the sandstone formation you can literally climb for hours without ever touching the ground - only stopping every once in a while on top of a tower to admire the view.

So if you are climbing addict and are comfortable soloing at around 5.8 - the hunter rock circuits have the longest continuous "fix" of fun moves on amazing rock anywhere.
