With sixteen teams playing on the first two days of the tournament, it is necessary for the AAABA to use multiple fields. The Point Stadium is the primary field and is used for all Johnstown games as well as the championship games. Roxbury (located south of the Point) and Arcurio (located north of the Point) are secondary fields that host games for the first four days. The remaining five fields are outlying fields that are only used on the first two days of competition. Franklin and Pitt-Johnstown are located in suburbs of Johnstown, while Portage, Lilly, and Revloc are all located about 30 minutes north of town.

Admission to AAABA games is free, except at the Point Stadium, where a small fee is charged to help support the Johnstown Old Timers. While each field offers a varying amount of permanent seating, all have spaces for lawn chairs. The geographical spread ensures that local residents in all parts of town have a field close by where they can attend games.

Originally, the tournament was to be awarded to a new host city every year. In 1946, Washington, D.C. hosted the tournament. However, amateur baseball received little attention in the larger city, and it was later decided to hold the tournament in Johnstown every year. The only exception so far was in 1977 when the city of Johnstown was flooded, forcing tournament officials to hastily relocate the tournament to neighboring Altoona, PA.
