I used a 7 iron from the Blue Tee Box (157 Yards) on the 8th hole at Butter Brook Gold Club in Westford, MA. The pin is behind the bunker on the left hand side. When I teed-off, the ball drew left towards the pin. I heard the ball hit the pin, and assumed the ball bounced onto the green somewhere. When my friends and I went towards the green, I only saw my friend's ball and not mine. So then I thought maybe the ball went into the hole. I ran towards the pin and looked down at the cup and I see the ball inside! I was so happy, I couldn't believe it. This was my second hole-in-one in the 12 years I have been playing.
