Vt. Stat. Ann. tit. 31, § 441

The officers of a town fair association may regulate and prevent theatrical, circus, or mountebank exhibitions and shows, or traffic in fruits, goods, wares, and merchandise of whatever description, the trading of horses, and games of chance, on fair days, within a distance of 200 yards of any highway leading to or passing a fairground, if in the opinion of the officers the same would obstruct or interfere with the free and uninterrupted use of the highways.
