Playing a Donald Ross course, Brightwood, in Dartmouth with my brother-in-law. First time I had ever played there. I hit a good shot that drew back to the flag. I thought it would be inside 10 feet. I saw it land and then disappear. Since I had not played there before I thought it might have caught a little slope and rolled out of view. My brother-in-law and the other 2 members we played with were both pretty certain it was in the hole. Sure enough when we got to the green it was in the hole. I retrieved the ball and set it aside in my bag so I didn't accidentally hit it again!
