To be ignorant and to have little common sense is one thing, to write a story about it to tell the world is another.
If you're getting a package deal to go to Vegas, add a rental car, they are cheap. My experience in just about anywhere I go they are $14 to $40 a day.
Then pack a cooler to put in the trunk. Park close to the entrance so that you can stroll back out to your car for a lunch/snack break. If they allow you to enter with bottles you are drinking from, just open the 4 bottles, take a sip, walk through the gate, put the lids back on and put them back into your backpack. They knew about this because they were telling the people they gave the extra water to.
It has been proven over the years that spectators feel they have the right away over the competitors, so the need for stop signs and guards. You would not believe the amount of times we have been cursed for asking people to excuse us so that we can get our car out of our pits, to the staging lanes or back to the pits. Doesn't matter how nicely you ask. Some will outright refuse to move.
And by all means, everyone should be allowed in the staging lanes!

I will admit it is an inconvenience to have to actually walk to someone's pit area to visit with them.
Reserve seats keep you from having to arrive early and leave someone in your seats all day to save them. They don't cost that much more considering the convenience.
If you need to drink beer at the track, paying the high prices for them is warranted. It helps defray the cost of the added security needed to curb your surly attitude later.
Considering this "story" is published by a "publication" that also promotes events, you would think that the editor would enlighten this "writer" to some of the ways of the world. But I guess that would take some common sense on someone's part.
