Theatre groups include the Janus Theatre Company, Elgin Theatre Company, the Independent Players, Children's Theatre of Elgin, Fox Valley Youth Theatre, and Nothing Special Productions. Together, The Hemmens Cultural Center and Elgin Community College's Visual & Performing Arts Center host dozens of performances a year by performers ranging from Chicago's Hubbard Street Dance Company to comedian Bill Maher. After losing many landmark businesses in the 1980s, downtown Elgin experienced a renaissance in the 1990s with the arrival of the Grand Victoria riverboat casino and improvement in the local economy. Many historic buildings have been transformed into stylish clubs and restaurants. Elgin's city parks include Lords Park, which features the Elgin Public Museum and a small zoo featuring a herd of American bison, and Wing Park, which includes a golf course and outdoor swimming pool. Other golf courses within Elgin include the Highlands of Elgin, the Elgin Country Club, and Bowes Creek Country Club. The Centre of Elgin, which among other features includes an aquatic park and a climbing wall, remains one of the largest municipal recreation centers in the United States. The Elgin Sports Complex on the city's southwest side offers ten lighted ballfields, ten soccer fields and The Hill BMX track. The complex hosts several local, regional and national tournaments every year. Elgin connects to Algonquin and Dundee to the north, and St. Charles, Geneva, and Batavia to the south by the Fox River Trail bike path. Although one of the largest and fastest-growing cities in Illinois, Elgin still retains some of the natural habitat diversity that first brought settlers to this area. On the east, the city borders the Poplar Creek Preserve, maintained by the Cook County Forest Preserves, which includes bike trails, hiking trails and equestrian trails. The Shoe Factory Road Prairie located in the preserve provides an example of the hill prairies that once dotted the region. Poplar Creek Preserves connects to the Spring Creek Valley Forest Preserve via a conservation easement covering parts of the Sears campus. Elgin boasts two highly protected nature preserves, the Bluff Spring Fen and Trout Park. For its size, Bluff Spring Fen has a remarkable number of distinct plant communities, including a hill prairie and a fen, or alkaline spring marshland, which is home to several rare orchids. Trout Park also includes a similar calcareous seep community, with the addition of a unique forest community of oaks, ashes, maples, and
