Bottle #2 in the photo certainly looks like shine. I wasn't willing to taste test it though.
-Jeff Scott Subject: Re: KR> Mogas Blues... continued Jeff I hate to disillusion you but up there in Arkansas they are running moonshine in those pumps. It’s kind of like our Coke machine back in college. Back then there was no cola in that Coke machine. It may have said Coke but every other can was Budweiser. First quarter got you a dummy can of Cola and the second quarter got you a Bud. If only a Bud was fifty cents today.
