DECEMBER ACE

So the weather breaks and the temp hits almost 60 time to try the prototype 2 test ball that TITLEIST sent me.
Play 8 holes hitting 2 balls and I'm playing well 3 pars a bridie and a double.This guy catches up with me on the 7th hole and I start playing the prototybe only.
A cold front starts moving in the wind picks up and its getting colder.Still hitting the ball well get to the 15th hole par 3 145 yards wind blowing 20+MPH hit a 6 iron into the wind the ball disappeared.The guy that I just met says it went in I say no the green slopes back there,as we walk up to the green we only see 1 ball.I'm thinking that i had hit it long nope in the HOLE.Second lifetime ACE both this year.O BTY been playing about 40 yrs.
