Ran across this Kickstarter. Living in the middle of the country, I can rarely get oysters in the shell for grilling ala Drago's. I can get good oysters and have done the "muffin tin" method, which works OK. So, when I saw this idea, I jumped on it. It has a long way to go to get fully funded, but you gotta start somewhere!
