Just stopped by the new Columbus service center on Morse Rd. VERY easy to find and much larger than the old service center in Dublin. Huge sign on the side of the road. 3/4 mile down the road from the new store at Easton Town Center. There are 2 HPWC's on the side of the building. Overall, much improved over the hard-to-find store in Dublin.
Here are a few pics which I added to PlugShare:
