It's certainly better to discover that my commuter bike has a flat rear tire on a Sunday afternoon than on, say, a Tuesday morning when I'm about to commute with it. But I'd rather not have the flat.
(You know how the bike mechanic at your local bike shop can change your flat tire in no time at all and make it look like magic? Me with flat tires is the exact reverse of that. I will forever be the last place finisher in any flat-changing competition.)
