I've generally not paid too much attention to the Corridor H discussion here, since it will primarily benefit DC area skiers heading to TL/CV/WG. However, I got a nice surprise when I googled directions to Wisp from Charlottesville - rather than the 4.5 hour trip I expected going via 81/522/68, google came back with a route that uses 81,  Corridor H and 219 and has an estimated time of only 3.5 hrs. If this is true, that puts Wisp in the same general range as SS and TL as far as driving times from Charlottesville go.
