Funny you should mention this, since I was just doing a TP day and talking to Alan about it. I don't know what "type" of horse will run well there (some grass horses have, too soon to tell what it means), but I'll tell you this for a fact-- they claim nothing changes that track, which would make it easy for others to make figures for it, and that ain't true. It DEFINITELY has changed speed, and not just from day to day, within days, quite a bit. There probably is something you could correlate it with-- heat, humidity, direct sunshine, something-- but it's moving around quite a bit. Which is a very good thing.
