Excitement on the Parkway

Today I was driving on the Blue Ridge Parkway southbound between the Mill Mountain Spur and Route 220. The time was probably about 11:45 a.m., give or take a few minutes. As I approached the turn-off to take 220 north, I noticed a number of vehicles parked on the shoulder of the Parkway on the northbound side. As I got closer I could see that four of the vehicles were Sheriffs' cars, and the fifth one was a blue SUV.

I rubber-necked a little bit, but I could not see what was happening. It must be something serious, I thought, to have four police vehicles responding. I mean, how often do you see that?

Does anyone reading this have any idea what was happening out there?
