The CC of Fairfax (VA) has a lengthy par 5 - 585 yds I think - #5, which has a blind tee shot over a ridge and a blind second over another ridge. During the 13 years I lived there and was a member, I don't think I ever heard of anyone being hit by a shot, but you did have to be cautious.
Typical terrrain for the DC area, several ridges cross the coursre property and the unknown original architect chose to play over the ridges with at least six or seven blind shots, rather than down the valleys which could be mucky with the clay soil there.
I haven't heard much good about the revisions Arthur Hills made a few years after we left in 1995. It is a very solid course and worth a visit when in DC.
