As of this afternoon, 3599 miles for 2010.
1069 miles on the V-Rex (short wheelbase) mostly commuting to and from work (suburban/urban).
2267 miles on the V3 (long wheelbase) suburban and rural riding, including club rides.
262 miles on the KHS tandem with wife/stoker. Late start on our tandem riding this year, after her surgery in the Spring.
This is the first year I've tracked mileage - I think the 2010 total is the most in recent decades but am not sure.

edit: I will try to add at least one mile on December 31.
