Combine remaining ingredients (oil through garlic) in a ziplock bag. Add shrimp to bag, seal and squishy to coat shrimp with marinade. Let stand 30 minutes on the counter or longer in the fridge if you have time. Remove shrimp from marinade and discard marinade. Pat the shrimp dry if they are too wet. Thread onto skewers. Grill shrimp over medium heat on natural gas BBQ until shrimp are pink & opaque (3 minutes per side).
