Details are still sketchy, but the Pittsburgh Randonneurs will be running a 2-day trip to Erie and back next month, in the form of back-to-back 200K brevets. The basic plan is to start in Cranberry, head up to Erie and an overnight at the Comfort Inn, then return the next day along a similar route.
The route will be fairly similar to that of the MS 150, i.e. reasonably mellow; no multi-mile climbs or Dirty Dozen-style hills need apply. It's rando-style, so fully self-supported (although, with sufficient interest, it may be possible to arrange a car to carry drop bags to Erie, but that's to be determined).
