THEME:   first word of a phrase involves Santa's sleigh ride   
GOOD ONES:     Breeder's Cup track   SANTA ANITA

BTW:   While the puzzle per se was not the best, at least it had a Christmas theme --- for which I am grateful: while I lack faith I do  appreciate our better traditions, and I think Christmas is the best time of year and should be celebrated at least for its cheer and giving spirit.            
RATING: 
 
   Three grins = Loved it; Two grins = Enjoyed it; One grin = A bit bland for my taste; One teardrop = Not much fun
