Bacon wasn't crispy and the shrimp wasn't overcooked.
A trick I saw on Good Eats is to put your bacon in the microwave (or I guess you could put it on the grill) for just enough time to begin to render the fat. Bacon should just be soft, but not beginning to fry. Then wrap your shrimp or whatever. Bacon and shrimp get done at the same time.
Good looking supper. Where did you get the skewers?
