GETTYSBURG, Pa. (AP) — Gettysburg is hosting an annual bluegrass festival not far from the historic battlefield.

The festival at the Granite Hill Camping Resort takes place Aug. 21-24, with more than 20 scheduled acts, including The Grascals, Rhonda Vincent and the Rage, and Seldom Scene.

Prices range from $20 Sunday-only advance tickets to $125 four-day admission at the gate. Fees for RV and tent campsites and hookups are additional. Discounted ticket prices are in effect until Aug. 14.

The festival provides no chairs, so bring your own. Blankets and lounge chairs are only allowed near the back or sides of the seating area.

The event will also include a Martin guitar raffle and a bluegrass academy where children from kindergarten through 12 years of age can learn to play instruments. Tuition is $25 but space is limited.
