Maybe they should just close the Fair entirely, as the whole point of holding the Fair and the sideshow attractions is to create spectators/viewers/watchers of the shows, displays, animals (if they still have them) other people enjoying the Fair. If they are trying to deter loitering around sideshows thinking that those lurking might be "up to no good", then have security guards to ask those people to move along or escort them to their car or public transportation if they are causing a disturbance. No need to fine and arrest Fair goers, unless you are really just rounding up people of color or other "undesirables".
Further, the notion that this would cost the County (taxpayers) nothing is absurd. Processing the paperwork for extracting the fines and chasing down the violators would certainly have a cost. And monitoring the bystanders at the sideshow would have to be a paid position or be included in any security contract. Oh, maybe you can just get the Fair-goers to turn in the other Fair -goers who might be lurking at the sideshow.
This proposal is ludicrous ( meaning: so foolish, unreasonable, or out of place as to be amusing; ridiculous) and seems to be typical of the "leadership" in the county, state and nation. You can't make this stuff up !

Side shows have nothing to do with the fair.

They are unsafe actions involving cars taking over intersections and doing donuts while burning rubber, etc.

Seeing people watch and shoot phone videos of the side shows bring only one thought to mind - what a bunch of morons and idiots.

Been There: What are you talking about? How did the fair even get into your conversation? I don't think you know what a side show is. You tube has plenty of videos on the subject.

The people that participate in such activities are irresponsible and inconsiderate. They have no regard for the safety of others or themselves.
A strong message has to be sent, unless it is, these activities will just move on and continue to other communities where the curious will attend.
I think that the proposed ordinance is a good start, to that I would add impounding the cars of the participants for six months.

I'm guessing that Been There has actually been to a fair in the past when there were side shows featuring attractions like the Bearded Lady, Alligator Man, and Tiny Tim in a separate tent at the fair. He hasn't quite caught up to the term Side Show as it applies to reckless, loud, dangerous, and pretty darn dumb (IMO) screeching of tires, burning rubber, closing down streets and roadways for what some younger folk consider a fun sport.
I'm also guessing Mike's to young to be familiar with those kinds of displays of persons with medical conditions that are now prohibited, as well they should be.
