The popular Rainbow 6 kicks off in the upcoming 6th race, a wide open five furlong turf dash for mid-level maiden claimers.  The pot began with a carryover of nearly $1.9 millions and figures to end up somewhere in the vicinity of $2.25 million before it's all over.  Salty will be most everyone's single in the 5th leg with relatively short fields in all but the finale making it near impossible for a single winning ticket today.
