If you haven't done this century, or are looking to do your first century, this is the one. It's relatively flat and easy and very well organized (the route is well marked and the SAGs are always well stocked with good eats and hydration). We do this as a group ride out of our LBS and it's a blast! Definately one of my favorite and most memorable rides every year.
Hope to see you all there. http://www.amherstrotaryclub.org/covac/
