Not sure how I missed this, but the Bisons repeated one of their best promotions early this month where they donned Star Wars themed uniforms for the benefit of the American Cancer Society. They used the same log as they did last time, with the AT-AT walker as the corollary for the Buffalo Bisons main logo. The rest of the uniform was white this year (black last time) and was made to look like a storm trooper uniform. Nice touch guys, nice touch.
Sorry to hear you missed this event initially. There will be another Buffalo Bisons Star Wars Night (the 5th year for the event) this year, on June 9. There will be a Star Wars themed jersey again, though the design has not been finalized.
