Carson, the former editor and publisher of the newsletter, established the park counting guidelines which requires seeing a Major League, Affiliated Minor League, Independent Minor League, or Collegiate Summer Wood Bat League Game. Note: Not regular college games.

To qualify for "Races & Bases" on Roaming the Raceways, a person would need "Twin 100's", the 100 tracks necessary for listing on the RTR site, and the 100 ballparks required to earn the certificate from Minor Trips.
