Unlike other travel bloggers who haven’t been to the places they wrote about and simply borrowed other’s photos for their posts, in my case, I made sure that I visited them all. All the unusual and weird places and roadside attractions around Southern Ohio, I have seen them with my own eyes.

If you are passing through Southern Ohio through any of these interstates: I70, I675, I71, or even I75 — there a number of quirky roadside attractions that await to be explored.

Here are my top weirdly interesting sights.

1. National Barber Museum

See the collection of over 61 barber poles, more than 800 straight and safety razors, razor strops, clippers, bloodletting tools from the days of the barber-surgeon, shoeshine chairs, spittoons, and historical barber chairs. The museum also has a barber library of over 400 volumes.

Address: 135 Franklin St, Canal Winchester, Ohio 43110. For GPS directions, here is the link to Google Map.

2. Antique Dolls at Mid-Ohio Historical Museum

Talking about a massive antique doll collection, the Mid-Ohio Historical Museum in Canal Winchester, Ohio has it all. Believe it or not, seeing dolls in various sizes and facial expressions, and yellowed with age in every corner of the museum, was quite spooky. It seemed like there were too many eyes staring at me at the same time.
