Math 252 Lecture 16: Monday , February 8th 1999.

Today a snowstorm hit the morning commute up Burnaby Mountain, leaving abandoned vehicles sprawled out all over the road. I have a 4-wheel-drive truck, but it's one of the old fashioned ones which requires the front hubs to be locked (from the outside) before the front axle can be engaged. I put on the parking brake and got out to lock the front hubs, but the truck started sliding backwards towards the car behind me! The road was so slippery that the parking brake wouldn't hold the truck! I jumped back into the truck and put on the brakes. It was at this point that my brake lights came on and and the pedal went down to the floor. The hydraulic line picked an interesting time to spring a leak! Anyway, I spun the rear tires and got over to the curb where the parking brakes would hold the truck, with the help of the tires against the curb. Then I managed to get out and engage the front hubs. After that, I shifted into 4WD and drove past the stuck and abandoned cars, and managed to make it up the hill. (Good thing I wasn't going downhill, with no brakes.)

Upon reaching the class, I found that only a few students had made it, mainly those living in residence. A bus was jacknifed across the road and the other busses had stopped running. I decided to cancel today's lecture, and extended the due-date for handing in HW#04 until Wednesday.

(Then I took my truck over to the Shell station to get the hydraulic line fixed.)
