Time trial?

The last time I had Allen over he told me that i should time how long it takes me to ride my gocart down the driveway into the side yard and back to the top of the driveway. My fastest time is 12 seconds. I was going about 30 or 40 the whole time. I did'nt slow down the whole time, so when I hit the hump in my laun I bownced out of my seat and onto the side rail of my gocart. Ow! above is a picture of Brin and me when I first got my gocart.
