You cannot play frisbee golf in a public park after dark.

The Law

In Bozeman, night-time games of frisbee golf—affectionately known as 'frolf'—are legally off-limits in city parks. This ordinance was enacted because enthusiastic college students were keeping neighbors awake with loud, late-night disc tossing. It is a rare example of a relatively modern nuisance law targeting a specific recreational sport.
