is there a way
 

i remember i used to give one of the guards 10 bucks and hed let me through in the wee morning and i watch the workouts and stand around claire court and just breath the air and invision this is heaven
the best part was being able to stay there all afternon and bet ,sit right in front of your car and they had 6 teller windows with a few tvs to watch

is there anyway a regular person can go back there and enjoy a day at the races?

only if you have a friend with access to the backstretch. trainer, owner, etc...
