Dave thank you for posting this and allowing us to print it. This is very valuable information. Regarding the Tracks that are of smaller size that you have commented that these are usually dominated by a handful of trainers, I tend to stick with Penn National and Charles Town, of course I also do aqueduct and such but for the most part my research and focus is mainly with Penn National and I have been studying charlestown. Is Penn National and for charlestown on this list? I apologize if that seems like a silly question but I don't see an abbreviation for Penn National and I'm not sure if Charles Town is up there.
