Hagerman National Wildlife Refuge is located on a portion of the Big Mineral arm of Lake Texoma in north-central Texas. Consisting of about 12,000 acres, the refuge provides a variety of habitats for birds and wildlife. Canada, snow, white-fronted, and Ross’ geese along with pintail, mallard, gadwall and other migratory birds by the thousands take up winter quarters or refuel for long journeys. Although they take top billing, birds are not the only attraction. Colorful wildflowers and prairie grasses provide seasonal food and shelter for wildlife. Butterflies, meadowlarks, and dragonflies flutter through the summer landscape. Bottomland hardwoods along the creeks attract a variety of wildlife including white-tailed deer, bobcats, river otters, turtles, and fox squirrels. Listen for the howl of coyotes at dusk.

The Sherman Museum is housed in the historic Carnegie Library building that formerly housed the Sherman Public Library. Built with funding from the Carnegie Foundation in 1914, the old Sherman Library building is one of a handful of remaining Carnegie Library buildings in Texas. In addition to exhibits on Sherman and Grayson County history, it has a large collection of fossils found in the area. http://theshermanmuseum.org/
