[Thunder Gulch]

I'm treating it the same way I always treated changes in surface- whether it be dirt to turf, mud, whatever. If they have proven they can or can't, then make the judgement accordingly. Otherwise you have to be flexible and see what else you can use to make sense of the whole puzzle. Colonel John, Pyro, and Coal Man are the ones with the huge questions on surfaces with the latter two having disastrous synthetic results after good dirt races. For them, the works at Churchill will go a long way to helping me decide who is and isn't a contender.
