Since today is US Bowling League Day, I thought it would be only fitting to look at the the Bowling Sports Pin. Requirement #2, has the girl research a famous female professional bowler.
I recommend that you begin with the PWBA (Professional Women’s Bowling Association). They have a webpage and it includes a listing a Hall of Fame inductees (here).
The US Bowling Congress, also has a list of hall of famers on their website (here), however it also includes male bowlers. The advantage to this site is that it provides a photo along with the brief bio on each bowler.
I hope you find these resources helpful in getting you started on the bowling sports pin. After you have completed your sports pin, consider using this tracking sheet to track your hours as you earn discs (here).
NOTE: The requirements have been simplified here. Please be sure to read the full text in the American Heritage Girl Handbook to make sure you fully understand the requirements.
