I am a fan of vintage/heritage baseball, teams playing 1860 or 1869 rules.
These are the two Cincinnati teams, it is awesome to get out there and watch these guys.
A good friend of mine Mark "Spider" Stenger plays for the Buckeyes, and part time for the Red Stockings.
It is fun to watch them play without the benefit of gloves, and playing the vintage rules too.
If you want a fun weekend thing to do, search to see if your area has a vintage/heritage baseball team and get out there and support your local team.
