Not a tractor story but stupid none the less.
SO my wife and I riding our bikes, I had a little trouble with something, had to tie my shoe or something and she got a bit ahead. So now we're racing right? I got up just as fast as I could go and we get to the point where the road narrows. I'm just about to hollar "On your left" when she looks over her left shoulder. At this point I'm SURE she's seen me so I make to pass her on the left. Thats when she takes a HARD left.
What could I do? I slammed on the brakes and creamed her. She dropped like a rock right on to the pavement, I got about 10' farther before the front wheel of my bike gave up on being round and caught in the front fork flipping me over the handlebars (I was going fast remember).
She got a pretty good gash on her temple, I wrenched my back pretty awful, but I still managed to carry her home. When I went back for the bikes I couldn't lift them up to put them in the truck, so I just chained everything together and went home. Took a day to heal before I could go back and get them.
Now we wear helmets and communicate while we ride!
