Since you already have the retail space, why not try it on a small scale. Stock a few of the things that people run out of and a few of the things that are needed - Hydrometers, Air-Locks, Tubeing and Chemicals. I'd put me a little sign in my Brew/Wine corner that says, "This corner of my shop is like your teeth, ignore them and they will go away, We will also". Give it a try, on a small scale, thats what made this country soo great, People taking a chance. It's kinda like Nancy said about the Health Bill, "Lets sign it so we can see whats in it." Give it a "small" try, you'll either make it or get your head chopped off.
And that's what I think.........
