On this, the last day of May in Kentucky, we are closing out Derby month with these two talented ladies on mules. Apparently, they were the winners at a “Mule Derby” held at Renfro Valley in Rockcastle County. Our mystery not only lies with the identity of these two derby winners, but also in the event itself. We understand that Renfro Valley still holds a mule related event each fall known as “Mule Days” – but is a mule derby still part of the tradition – is it connected to the current Mule Days at all? The photos looks to be from the 1920s, and held just outside the Dance Barn. OK – Rockcastle countians – help us solve this mystery!
