The "approach road" to my neighborhood is a couple of miles long and very straight. It's pretty rural, so we used to use the Bots Dots (the reflectors on the centerline, in case you didn't know that's what they are called) as pylons and weave in and out, as tight as I can, as fast as I can.
A few months ago I saw a crew sealing up the cracks on that road. The next time I tried my maneuvers...major pucker moment. The bike got REALLY squirelly and the road felt very greasy. It seems to have gotten better over time, but it's always in the back of my mind now.
