I had a '67 Camaro when I was in college, and had the engine rebuilt. After getting the motor re-installed, I was excited to fire it up and test drive it. Well, I had the hood partially open, but still latched, and as I cruised down the street the hood flew open... I'm really glad it was a quiet neighborhood street and no other traffic was around! It really sucked though because the hood never fit right after that, and it used to fit perfect.
