Advance ticket sales are underway for the Mt. Vernon BIG Spring Carnival, giving families a chance to save before the event begins. Now through April 28th, a sheet of 22 tickets is priced at 20 dollars, at least 10 dollars less than buying at the gate. The carnival runs April 29th through May 3rd and will feature rides, games, and entertainment for all ages. Organizers say family nights will offer one-ticket rides midweek, while weekend rides will require multiple tickets. Tickets are available online and at several local locations, with proceeds supporting Mt. Vernon Festivals Incorporated and future community events.
