I don't think we have the option of playing on Christmas. DRF has no listings for Christmas or Christmas Eve, but there actually are some pretty nice races on New Year's day so I wouldn't mind playing then, but I'm sure there are those that would rather watch football then or maybe recover from New Years celebrations.
I guess I'm showing my age. Haven't been to a New Year's celebration in about 30 years. Can't say I miss it much.
