While the experiment did have its flaws for the lack of a proper ballpark, it was about as perfect of a scenario otherwise, as Branch Rickey could have hoped for. It was indeed... an all inclusive Dodgertown. Branch Rickey had first come to realize the benefits of utilizing a military base during the war. The Dodgers were told in 1943 by Major League Baseball President Mountain Kennesaw Landis, that they would be unable to travel south during the Spring for the rest of the WWII (as was every other team in baseball). The Dodgers would have to find a place near Brooklyn to make camp. They found that
  place at the West Point Army facility in Bear Mountain New York. The Dodgers made their accommodations at the Bear Mountain Inn as well as some of the barracks on the West Point base. They made a little ballpark there just like this one, right outside the Bear Mountain Inn. While it wasn't perfect... it was freezing cold, covered in snow most of the time and without a legal sized ballpark... the seeds were sown for the benefits of utilizing a military facility for training their players.
