If a harness track ran on X-Mas day... would you bet?
I think I would not....
Christmas Day should be dark; BUT >>>
harness racing is missing a chance on Thanksgiving and esp. New Years Day. if you ever go to the casinos on those 2 holidays - the machines are full up. Thanksgiving, as our culture has changed, is a day of loneliness for people w/ family out of town, divorced, estranged and all -- and, New Years, for the more mature folk that no longer go out and party strong on NYE .. Both of these days could attract interest.
Now, the trick is only scheduling 5 races or so at each track - and, alternate among those tracks by post times - and, c'mon w/ enticing purses and competitive, interesting conditions.
