So, I have two stories.
First one is when I fended off 3 rottweilers out in the country on my BMX bike. Well, I didn't really fend anything, they started biting my pants, legs and pedals so I jumped off and just charged at them maniacally. They didn't see that coming and ran away.
Next one is a funner story.
I was riding my 12 speed Peugeot along at like 7am and something jumped out of the bushes on the side of the highway. It looked like a small horse! I hit it doing 35-40, and it just skidded on it's nails. Granted to say, my testicles sucked up into my lungs - I was scared. Then some chick comes out of her house and got the dog. We ended up becoming friends, and the dog ended up being a sweetheart RottPitt with a head bigger than a basketball.
