The city of Brighton will be letting loose this weekend with their annual celebration of Whoopee Days. Brighton Chamber President Brian Arnold says they use a tried and true formula of events that always brings in a good crowd. Arnold says participants will be treated to a variety of events and activities, including the always popular mud run and armband night where an armband will allow you to ride as many rides as you like for two hours. Arnold says hes also excited for the country/western band Lockren to perform on Saturday night during the street dance.
