They played their home games in Old Orchard Beach (OOB). When baseball was no longer being played at ‘the ball park’, it became a spot for outdoor concerts for many bands of the era. I personally saw Aerosmith, Tesla and Motley Crue all perform at the ballpark one summer. Minor Legue baseball returned to Maine in 1994 when Portland became the home for The Sea Dogs. The Sea Dogs were affiliated with the Florida Marlins until 2003 when they became part of the Boston Red Sox system.
Although I never made it to the ball park in OOB to see The Guides; I remember watching some games with my late grandmother on TV. She loved baseball. I saw the Maine Phillies play a couple times in 1988. Had Tommy Barrett (brother of Red Sox 2B Marty Barrett) sign a baseball for me. To this day, The Maine Guides logo is still one of my favorites.
