My club did not reduce the number of tournaments we fish 14, but we kept them all within our "home" region which consists of 5 major impoundments. So travel is at a minimum and most of the members say it does help.
As far as the non-boater fee, what do you mean? Do you charge the $50 above and beyond the entry? If so don't you think that's a bit much? We suggest that non-boaters chip in $25, and most give $30. Which in all honesty covers about have the cost of the gas and oil for the boat.
