I'm a bit embarassed to post in this thread, but I figured I would because then others might feel better...

200 miles, commuted 10 times over the summer.

I have a list of excuses longer than my arm, though!

a: just bought a house
a1: moved in with a fiance and 2 kids
a2: lots of nights of dad-duty while (see a3)
a3: fiance was in school in the evenings.
b: it was too hot
c: my bike broke (bottom bracket bearings wore out)
d: I inhaled a bug and choked to death
e: work hours changed, couldn't justify cost of a good headlight (see excuse a)
