My 1st Shot Ace on a Par 4 Hole

On June 11, 2013, I was playing golf in Costa Rica at the Papagayo Golf & Country Club on a company Incentive Trip with 7 other buddies. My foursome teed off second on the Par 4 #1 Hole, a 248yd dogleg right, blind tee shot to an elevated green. Unseen by me, my ball bounced onto the green while the first foursome was putting and rolled into the cup for my first hole-in-one on a Par 4. (2nd ace overall.) FYI, I birdied the next Par 3 hole and was therefore 4 under par after only hitting 3 shots...my lowest ever score after two holes.
