Fairways that look like this.........

Have a tendency to grow stuff like this, pythium fungus.  Warm nights have produced long durations of leaf wetness and.......whammo, pythium and brown patch.  We found these little monsters on seven red, the tight trees create an environment with poor air flow, and turf that is comprimised since it is competing with trees for light and water.  Heavy rains would not have been good.  We will be restricting cart traffic to the path for a few days to allow the turf to recover.  
See you on the path,
Turf
