I live in the Cincinnati area and want to play and learn about X-wing. Are there any groups in the greater cincinnati area playing?

I thought FFG had a store locator, but it turns out that's just for their single official FFG store.

Wizards of the Coast, makers of Magic and D&D, does have a locator.

No promises, but some of these places will very likely have the droids you're looking for.
