I'm hovering around 1750 miles right now. Still 2 commuting days to go. I did over 2300 in '04. I lost a bunch of miles in '05 due to working from home for about 6 weeks in prime commuting weather (August/September) due to my wife's back surgery. I sloughed off a lot of other days too.
I'm shooting for at least 2000 for '06, I'd like to hit 3000+. Someday I'd like to hit 4000.
