Got my first ace ever today! There is a temporary course set up for ArtPrize 2022 here in Grand Rapids, MI ( https://www.dgcoursereview.com/course.php?id=13435 ). The hole I aced is about 100' and looks like a metal cow with the center cut out (just look at the course page if you're scratching your head ). Not the most difficult course by any means, and it will probably be gone in 2 weeks, but there was a defined tee area and a defined target so I'm counting it! The other funny part was that I threw a disc that was not mine, but rather was borrowing from the bin of available discs at the course - a Westside Discs Swan. Hoping for an ace on a normal course some day soon.
My son aced the Monster on a practice shot, caught here on our GoPro: https://youtu.be/cqhWtzOG7ow?t=334
