Vintage Tractor Parade ~ Bostwick Cotton Gin Festival. Great vintage tractor parade, great fun was had by all at this event. The Bostwick Cotton Gin Festival began to save the Susie Agnes Hotel in the late 80's. Thanks to local residents, money was raised to purchase the hotel from a private owner and restoration began. The festival centers around an operating cotton gin, tractor parade, arts and crafts and live music.
