Back in the 80's when I was young I decided to open my bike up a little to see what she'd do. We rented a farmhouse on a lonely blacktop so I thought what the heck.
Got it up past 95 and was coming up on our corner so I backed it down. As I slowed down the bike started to wobble in the rear end. Got it stopped and found a nail in my rear tire. Since my daughter was less than 2 years old I considered it a sign from a higher being. I never screwed around like that again.
