I emailed my local government to ask about whether it is allowed to walk on the trails at night because the signage at one of the places I like to go during the day says that the trails are only open from sunrise to sunset, and it is apparently a county wide rule.
We're kinda lucky here in that, while many parks technically close at sunset, there's a growing number of bike trails being built on old rail lines that go through some scenic/wooded areas, and those don't really have time restrictions.
