Came up on some dead animal remains on the GW Parkway this morning at 0530, quickly decided not to swerve because I could have lost control of the car. Blood, hair and other smeared across the undercarriage, transmission housing, suspension components and exhaust (so it stinks). The guys at Champion Auto Wash in Tysons were nice enough to power wash as much as they could and let me run through the wash three times to go over the undercarriage sprayers, they were excited to see the car and wanted to help. Bought a shop jack, jack stands and some industrial citrus cleaner and I'm going to spend a few hours cleaning the whole undercarriage by hand.
