Who wants to waste the time to figure out the tire repair order of the day?
Gee, how many tubes should I take today? Should I add an extra Co2 cartridge, or just leave it at home and take only the pump? Are these patches any good? Who else is going to be there? What's the weather like, right now? How about later? Will I be gone long? How remote is the ride?
What's SWMBO doing today? Is she going to be available? Will there be cell service where I am? Will she have cell service? What if she's not around then? What if I'm riding when I'm supposed to be at work? What friends could I call if I royally screw this up?
Should I bring cleat covers in case I have to walk? Can I walk in these cleats? Are these my favorite socks? I don't want to ruin them.
That's just too much work. Load the kit up, leave it on the bike, and rock on. Prepare for the worst, hope for the best. And don't impose the consequences of your bad judgement on other people.
