Even though it is one of my favorite par 4s in golf, if it were up to me, I'd build a tee around 30-40 yards behind the current tee. My first rounds were played at Riv in the mid-80s and think the distance gains from equipment have made a difference in many subtle and not so subtle ways. The hole still holds it's own fine, and many would point to that, but I think the hole would be better with a tee 30-40 yards further back (or if it were possible to re-do all the land move the green complex (and everything else) 30-40 yards further).
