Sat 9/7/13 Montgomery, Somerset County NJ Sourland Spectacular
This one looks pretty good, near Princeton, 4 routes, 23-mi to 63-mi with some climbing. Good cause, supported, $40 day-of reg. Good info at the site.
Edit: There is a historic component - rides go past the Lindbergh home.
“Bikers also will ride by historic sites such as the Charles Lindbergh estate, site of the infamous kidnapping.” - See more at: http://spcnj.typepad.com/spectacular....yS7jTIBY.dpuf
