Burning Flipside here in Texas has had a lottery system for the last few years due to not being able to exceed 2500 people on site or be under the TX mass gathering law. They make the lottery a little inconvenient (sign up in early January, mail in a money order during one week later in the month, have the MO returned if you don't get tickets). They also have a no scalping policy and regularly go after sales on Craigslist and other sources for more than face value.

Sorry, what? have all major sporting events been cancelled too?

No, it doesn't permit gatherings of more than 2500 people to last longer than five hours without a lot of overhead (money and paperwork):

no, it's just that when you exceed 2500 people, a bunch of special provisions come into play, like having to provide water, security, vending, etc. that clash with the self-reliance/gift-economy aspect of a burn.
