Turkey Talk at Guadalupe River State Park is a Thanksgiving Day program all about wild turkeys, their habits, calls and other fascinating features. It takes place at the amphitheater behind the Discovery Center at Guadalupe River State Park in Spring Branch, just outside San Antonio. It's a relaxed, nature-focused way to start the holiday, and the park's Hill Country scenery makes it feel like a real outdoor adventure. Admission is free with park entry.
