Though, Dayton is further you should really try to go there at least once in your life. The staff there is AMAZING. They can answer any question you might have, regardless of how weird it may seem. I'm fairly certain just about all the employees on the home brew side do it themselves so it's fun to hear about their latest creations.
Now that I think about it I can recall a Cincinnati Home Brew store with the biggest selection I've ever seen in real life. I'll have to do some research to find its name again. My boyfriend and I met the owner at a beer event this September.
I love jungleJims! I once went there and was given scientific explanation on why some people love hot sauces and keep moving to hotter and hotter by an employee at a sample stand.
They also have the best of international foods from all over the world all in one place, which definately beats running from store to store if you have exotic tastes like me.
