During the summer, Omer is a popular weekend getaway for those looking to unwind by canoeing or tubing down the scenic river. There are also miles of unspoiled forests surrounding the city that bring in deer hunters from around the country in the fall. Hunting is such a popular sport that the local school in Twining, Michigan closes for the opening day of deer season rather than face the 50% or more absentee rate that would otherwise occur. Winter also brings snowmobilers and ice fisherman to the surrounding area, though not typically the city proper.
The first is the story of the "cussing canoeist", the man who received a ticket under a century-old law for shouting a long stream of expletives in the presence of a woman and her two young children after he fell out of a canoe on the Rifle River. The ACLU intervened on the canoeist's behalf and got the law struck down in an appeals court.
The second concerns the successful secession of two households from the city because the City of Omer was charging them a water tax while refusing to deliver water service to their property.
