By "ahead" I mean "three feet ahead" and by "off" I mean "liquid."
I cross the boundary, and my wheels are immediately six to eight inches deep in wet cement. "Shiiiit!" I think, as I bounce on through, feeling the pedals getting harder and harder to push. It's a good thing I was already going pretty fast, or I'd still be there. I think the pond was ten or fifteen feet across, so I had a few seconds of panic to allow rzr_grl's offroad adventure to replay in my mind. As I bounced up over the lip on the far side of the pit, I tossed a glance over my shoulder and yelled "sorry!", only to see a couple of construction guys screaming at me and waving their arms. I pedaled faster in case they decided to pursue, wondering if my gears were going to solidify before I could escape.
At least there weren't a couple of guys crossing the street carrying a plate glass window. That would have been even more of a slapstick cliché than this was!
