Last weekend of September in Sand Valley on a father/son trip with two best friends and our 5 boys all in their 20s now.
Standing on the 14th tee at Mammoth, it was SO still and quiet that it actually felt loud....if that makes sense. There was literally no noise of any kind. No birds, no cars, no white noise, no distant noises...nothing.
Our ears strained to process this. It was eerie...and very, very cool.
