Javelina HD Fall Freedom Fest & Trunk or Treat at Javelina Harley-Davidson is a family-friendly Halloween festival in Boerne, just outside San Antonio. Hosted at the Harley-Davidson dealership, it's a spooky-fun way to spend Halloween afternoon. Pumpkin decorating is free, and there's trunk-or-treating, a costume contest and bacon-wrapped chili cheese dogs for the whole crew. Bring the kids in their best costumes, grab some candy and enjoy the motorcycle-loving atmosphere.
