I once was playing Belmont DGC in Dayton, OH and a storm was rolling in. I was there for business and it was the only chance I was going to get to play. It was in the summer and I decided I didn't care if I was going to wet so I headed out and got started. I made it to hole 12 or 13, and then all hell broke lose. The wind was so bad and it was raining so hard that I couldn't even tell which direction to head back to my car. Since I had never played this course and couldn't see a thing, it took me probably 15 minutes to find my way back to my car. There were several lightning strikes very close and I wouldn't have been surprised if it started hailing (it didn't). I thought to myself "well that was dumb" and was thankful I made it back to my car in one piece. Weather is very unpredictable and I personally think it was the right call. I don't think there was enough daylight to complete the round. Especially if it was stopped due to lightning and then wait a half hour and restarted again. Now I know several of us were on the far side and couldn't hear the horn and kept playing through and didn't wait the half hour. We might have been able to finish the round, but I know we still had 6 holes to play at 5:15/5:30 pm (when we finally stopped). The first round took us a lilttle over 3.5 hours to play in much easier conditions, which means if we played the final 1/3 of the course at the same rate it would have taken an hour and 15 minutes. I'm guessing in those conditions it would have taken us at least an hour and half if not 2 hours and I'm pretty sure would have been very, very dark.
