You usually don't see too many of those, but on Opening Day a few years back, i recall being parked near one. The guys just left it in the back of their pickup truck(similar to the one in the picture, but had a brewers flag flying on it), and charged people $2 to use it(they told me it was paid off within the first 2 hours of tailgating). When the lines are 20 minutes long just to get into the normal ones, you'd be shocked how quickly folks will pay for instant access.
