Fix now? or ride now, fix later?
I suspect we've all had decisions like this one. Tire was fine on previous ride, but the bike sat unused for 3-5 days, and had lost almost all its pressure. Do you pump it up and ride anyway, or do you take the time to find the cause and fix the flat? And if you pump and ride, and make it home OK but the tire's low in the morning, you've got the same decision to make.
How long would you (have you) let it go on like that before you fixed the dang thing?
