With high gas prices........

What if all boat ramp owners waved ramp-in/use fees?

Would they sell more gas and stuff at their docks if the customer got a ramp-in for free?

Conversely, if I don't want to pay the high price to ramp in and want to save that money for boat gas or a meal, how can I buy it from your dock if I ramp in 10 miles down the lake?
