Isn't the whole point of bringing a cooler in to save a few bucks?? Why would anyone want to spend $15-$20 to pay a tax on that?? heck they probably don't even have that much invested in the contents of the coolers !! The larger sporting venues charge ridiculous prices for food and beverages...the smaller ones like these good tracks we race at are very reasonable at the concessions (excluding alcohol, because I don't know who sells it and/or what they charge) for food and drinks. If people want or need to bring their own in, so be it....as long as it complies with that tracks rules.
