Hell, tubing is more fun than surfing and if you disagree you're old
Nothing quite like putting the madman behind the wheel and holding on while actively trying to be killed on a tube lolol

I've got a little rechargable pump that works ok, not quite fast enough but it takes up no room and lives in the glovebox. Ran a while season on a charge, but we only tube 5 or 6 times a season probably
