The Las Vegas City Council has passed an ordinance which will require downtown street performers to register with the city, and will also restrict them to assigned circles six feet in diameter.
There are 38 such circles, and each performer will be restricted to a two hour time limit in each zone. Performers will be rotated to prevent someone from monopolizing a highly desired space.
The Las Vegas Strip will not be affected by these new rules, since it's outside of city limits.
I think most people will agree these rules are a good thing. People dressed up in Mickey Mouse costumes and shaking down tourists for photos and tips is a bad trend. This will hopefully make the buskers less aggressive, and help clean up the image of Fremont Street a little bit.
