It's Thunder weekend 18th century style at Locust Grove, commemorating the arrival of Revolutionary War troops in 1778 under the command of General George Rogers Clark. Talk to the soldier-reenactors and their families, learn about battle tactics, and participate in a wreath-laying ceremony honoring Clark, with a 21-gun salute. You can chat with the women in the hearth kitchen, the doctor will demonstrate how he'd remove musket balls from victims, and kids are encourages to sign up as new recruits. Concessions available. (This event does not include battles - it's all about the American troops.)Special pricing this year: $4 for adults, free for children 12 and under, historic house tours included.
