I myself am new to the Columbus area, and Meetup has always been a great way to meet people and do things around a city with new friends.
I am already a member of a Mid-Week, After-Hours group and it has been a success. the host of Drinks After Work as inspired me to get involved and to expand on that to start planning events on the weekend.
The kinds of events I have in mind are: Local concerts, discussions on patios, trying new restaurants (and old ones, too). I would also like to include some active events like Rafting, zip-lining, etc...
I am discovering that Columbus has a lot to offer and I am sure there are like minded people in the 30-50's age range, that would like to experience the area in a group setting.
Join up and send me your idea.
I plan on the first group to meet in February at a location to be announced.
