Can you explain the 6 Turf Courses of Laurel Park?

The Laurel Park turf course area is 142 feet wide. We have the ability to move the portable rail so there is no overuse of one area of the track and the 6 turf course names and locations are as follows:

On the rail: All Along
17 feet out: Bowl Game
35 feet out: Kelso
52 feet out: Dahlia
70 feet out: Exceller
87 feet out Fort Marcy
