Denny,
How did your knee do the rest of the day? Do you think that your knee will be stable enough that your foot can hold down your pump long enough to get your 8 psi into your cross tires for Chuckie's?
Not sure what would give out first, the knee or your arms because that's at least 2 or 3 pumps (actually that's a solid sneeze!!!!). I'm just messin' with you, roll with what works.
