It means dust off your boots 'cause this is going to be a hoedown! Think of semi-formal or dressy casual but add a western flare. Sturdy shoes are encouraged as parking lot used to be a pasture and the road from parking lot to venue is a bit of rough terrain.
If you would like to be close to downtown and where the families of Jackson & Emily will be staying, we encourage you to book a room at Hotel Windrow. The Best Western is another very nice hotel which is the next closest to downtown and to the venue.
