spaces to people in situations like yours.
I own a boat and would rather pay the space rental than worry about what bozo will do to my boat when he's out in it. Or the people he'll injure and I get named in the wrongful death suit. NO WAY I'm lending my boat out to some rando in trade for parking space, unless it's a john boat with a 5hp weedeater motor.
Does your insurance know you're going to do this?
