Many years back we put a portable course in a cove early one morning hoping it was the right spot for the forecasted wind. Along comes a pontoon boat trolling with side rigs and down riggers, he shouts at us: "you guys are using an awful lot of lake!!" This lake happens to be 9 miles long and 2 to 4 miles wide. He was heart attack serious, I don't think any of us could even come up with an answer,
