The estate contained Macomber's residence, stables, dog kennels, as well as a horse track, steeplechase course, and golf course.

[4] Racing began in June 1927,[5] and Macomber opened Raceland to the public free of charge for one day of the annual horse meet.

[4] On August 1, 1930, a fire that started in the hayloft resulted in $200,000 worth of damage as well as the death of Macomber's favorite dog.

The stables and club house were built with the same plans, but instead used brick, stile, steel, and concrete to make the structure more fire resistant.

[4] The steeple of Macomber's home was topped by a weather vane depicting his most famous horse, Petee-Wrack,[1] a half-brother of Triple Crown winner Gallant Fox.
