Track Ratings?

[danddiver]

I remember seeing a list that rated all North American tracks like Belmont and Santa Anita were "A" tracks Calder would be probably a "B" track,etc.
It may have been based on purse values or something like that.
It was basically a rating of the quality of tracks.
Does anyonyone know where I can find such a list?
Thanks in advance to all.

That is what I was looking for and I thought I remembered it being from ATM.
Good memory!
