Caca happens. about 1/2 mile out of the gate, I brake and feel them slip. Great. It's pouring cats and dogs and I need my brakes. I have 7.5 miles to go. I'd been fooling with the front brakes a couple days ago so I check them and the pads have spread apart. So I get out my trusty allen wrench. What, it's not there! Argh, it dropped in the muddy grass while I was fumbling with the zipper on my pack. I loosen the screw on my Avid Shorty 4's and . . . the screw totally sheers off!!! Damn!!! I'm screwed!!! What to do??? My wife already left for work. OK, find another screw. Water bottle screw too big. My eyes scan the bike for extra screws. Ah, the tagalong hitch. I frantically unscrew one of the screws, already late for work. It fits!!! YES! I'm back in business.
