In early May about 15 years ago I was playing at the Garland Resort which is about 3 hours north of Detroit. This was a yearly weekend outing, 36 on Friday and 36 on Saturday but in Michigan that time of year is hit or miss. That afternoon was sunny but about 40 with periodic snow. It was great fun due to the nature of the foursome and we drank a lot of hot chocolate that day. I don't mind playing when it's in the 40's as long as the sun is out and the wind is down.
