I played Philly Cricket a few years ago. It was a beautiful September evening, and folks were dining on the lawn behind the green. My 20 handicap buddy laid up before the stream fronting the green. He took out his sand wedge, saw the folks behind the green, put the ball in his pocket, took off his glove, and picked up his bag. There was no way he was going to skull a shot into the crowd.
The ninth green at Sedgefield is pretty close to the clubhouse. I'm not sure how many feet it is, but it feels close. My five-handicap playing partner thinned his sand wedge from off the green into the clubhouse. I kept with for the sound of ball into window, but thankfully it missed. He wouldn't go get his ball, so I did.
I am not sure how close is too close, but 45 feet is on the edge.
