A flat tire

On my way home from work I had a little mishab; a flat tire at the right-front of the car. I was driving on I-90 behind a truck waiting for the left lane to clear when out from under the truck an object appeared in the middle of where my tire was gonna go... I think it was a piece of an exhaust since it looked round and black with some sharp endings. Since there were cars left and right of me I had nowhere to go but over it. A sharp 'clunk' and it was done. The tire held on for a little while, but I felt the car pull to the right and after about 30 seconds I heared the noise and the 'Low tire pressure' light came on. Fortunately I was just ahead of the E152th Street exit on I-90 West so I could immediatly pull off the Interstate onto the off-ramp. Parked the car on the shoulder (so I could mount the jack...) and went to work. An off-duty police officer just happend to drive by and offered some well received assistance. Eventhough you know how to do it, some help and advice from people who see and do this almost daily is never a bad thing. After about 20 minutes the deflated tire was in the trunk and the emergency tire (one of those pathetic small, but much appreciated bicycle tires) was mounted. Tommorrow we'll have it fixed properly. Good night, folks.
