I changed out the timing belt in my 1979 Civic on the side of I-275 in St Pete, Fl
I already knew the old timing belt was going bad, and I had planned on changing it after work in the parking lot, so I had the new timing belt and my tools in the back of the car, and the cover was already off. Unfortunately it broke before I made it to work.
Spoiler alert: It's not a fun job changing a timing belt out for the first time following directions in the Chilton's manual while up under the car and getting sand blasted the whole time by morning rush hour traffic! Did it in about an hour, though
