Cut slices of bacon in half. Cook bacon half way (should not be crisp). Combine Jack Daniel’s® Barbecue Sauce, lemon juice and garlic powder (pour half of mixture into separate bowl for use later). Dip shrimp into half of sauce to thoroughly coat. Wrap each piece of shrimp with ½ piece of bacon. Place on skewer (leave small space between pieces). Brush grill with vegetable oil, place skewers on hot grill and baste with remaining sauce mixture. Grill for approximately 4 to 6 minutes.
