There are some around here that are too...there are factors other than syringing that can help them withstand the heat....type of bengrass, strength of the plants, how old are the greens, how is the drainage, how low were they cut, how much foot traffic, among others I'm sure.
I went up to Grandover during the summer and theirs were in good shape although a bit high and slow but that's to be expected....
What courses do you play there? I hear Stoney Creek has reopened...have you seen it?
