Saw this post on the Radford Facebook page regarding parking:
There is a portion of the main lot that is blocked off. However, there are some makeshift lots further down and also around the side and back of the school, so there should be sufficient parking, but some may have a longer walk.
Me again: I actually live near Christiansburg and go through there all the time. Unfortunately I'm out of town for work starting tomorrow or I'd ride through there and get a first-hand report.
