Along the lines of Bob's Porsche photo.
Just riding along when the clouds start turning darker and darker, the amount of lumens is such that you wouldn't know what got served for dinner. Detour around the usual residential construction. No problem, I found a nice trail for a detour. Then in the middle of it, where you cross a street, caution tape across my path with what looks like sand in front of it. WTF, a detour on a detour? No way! So I dismount, shoulder the bike to get over the caution tape, take a step, and...you guessed it. Concrete!
Shouldering the bike was fortuitous and I made a good move in jumping across once I realized what was going on. Next week I'll have to check if my dufus move got eternalized. The shoe was cleaned in the wet grass easily enough.
