Sarah, we have a couple different knitting groups that meet around town in Columbus, depending on where you are. I'm at work, so I can't access the meetup.com group info, but we have a really great group that meets in a few different places (east side, downtown, north side etc). We have a blast! There are also a couple of great Stitch N' Bitch groups that meet around town. If you are interested, when I get home I'll send you links!
In addition, Heavenly Creations (on 5th Ave) has Knitter's Night Out on the second Friday of the month and Knitter's Day In on the second Saturday of each month. I have a lot of fun there! Knitter's Mercantile (on High Street near Worthington), another beautiful LYS, has Sit n' Knit nights the last Monday of each month I think? I can't usually make those, but I've heard they are fun and crowded I love the shop and manage to shop there and sit at their big back table for a while every time I'm there, so you almost always find knitters willing to answer a question!
We have an outing planned to the Yarn Market warehouse this coming Saturday (they are giving us the full tour!) if y'all want to join in, it's on the meetup.com group calendar!
