The Sheridan Farmers Market (formally the Grinnell Plaza Farmer's Market)  hosts local growers and local artisan's providing fresh produce and other foods, crafts, demonstrations, youth activities. Also local musicians frequent the market to provide a festive atmosphere.  The market is held every Thursday and runs from mid-July to mid-September, at the Whitney Commons.  "In 1992 when a group of citizens interested in participating in the Downtown Master Plan met at a town meeting held at the Historic Sheridan Inn, it was suggested that Grinnell Street be the location of street fairs and public art. In 2001, the Grinnell Plaza project, which was funded with private donations, grant monies and City monies, made that dream a reality. The next step towards completing that dream was the addition of public art.
In 2001, Mayor Wilson formed a public arts committee with a specific mission to promote and select works of art for Grinnell Plaza and other areas of the City." (Downtown Sheridan Association: 2005)
