Sighting on 08/30/11 in Burlington

This morning at 11:40, while driving to a doctor's appointment I saw a mountain lion run across George Washington Tpke near the intersection of Belden Rd, in the direction of the fish hatchery. It ran across about 100 feet in front of me, was reddish-brown in color, maybe about 100 lbs, and had a tail about a foot long with that distinctive black tip at the end. It was gone in a flash, but after looking at the photos on this website I'm positive it wasn't anything else.
