One thing about Huntersville/Cornelius is that there's already a shop in Cornelius (Alternative Beverage, part of ebrew.com). I think they're going out of business though. It's good in the sense that you'd be losing competition, but bad in the sense that the location might not be able to sustain a full-time shop. It's also possible that they just don't run the shop well enough. If you haven't been there before, I'd recommend stopping in just to get a sense for how they're running the shop and how you can do better.
Ive been shopping with them for 20+ years. Know the owner personally, he's had a monopoly for way too long. He's very wishy washy at 71, they are closing but we will see. Either way, bring it on.
I haven't thought of everything (like everyone things) but Im rolling with the punches.
