My 2nd hole in one in less than 2 months

this is a blind shot because the green is in a valley and there is a hill that blocks your view of most of the green. the green is very hilly and an easy 3 or 4 putt at times. I hit a smooth 3 iron with the breeze in our face to the 176 yard hole. Did not see the ball anywhere when we got down to the green and my playing partners said to look in the hole. What a surprise to see it there. I was using a Velocity ball. I will never forget this!
