Omer is a city in Arenac County in the U.S. state of Michigan. As of the 2000 census, the city population was 337. As of January 2006, it is the smallest city in the state. Like many small towns in northern mid-Michigan, the height of activity in Omer centers on an influx of people during the spring and summer. The Rifle River that intersects the city attracts thousands per year during the sucker season. Folks from all over the midwest and Canada line the shores and engage in the sport of sucker fishing in the spring. Up unil the late 80's, Omer held an annual Sucker Festival, but it was eventually ended presumably due to lack of funds. 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.
