RENO, Nev. (KOLO) -- Trick or treating is fun, but some people believe there are unwritten rules everyone should follow.
One of the rules a few homeowners in Reno say is not to touch Halloween decorations. Also, not walking on a homeowner's lawn and use the walk path instead.
Another rule homeowners say that is not known is not to ring the doorbell after 9 p.m.
But overall, homeowners say always be kind, say Please and Thank You and most importantly, have fun!
