What made me realize Gwangju Songjeong Station is truly on the outskirts

It was the fact that Gwangju Airport is actually closer to the city center than Gwangju Songjeong Station.
The Sangmu District is in a location where you have various options, including Yusuk Hair.
Conversely, this means accessibility to Gwangju Airport isn't bad.
While Gwangju Station is located in the downtown area, it isn't on the Honam Line, so it's a shame that it isn't treated as a KTX station...
Also, Yusuk Hair is a 10-15 minute walk from Nongseong Station; it's manageable without luggage, but the distance feels a bit awkward if you have any.
To get to Champions Field, you have to take a bus from Nongseong Station, but there is an overpass between the Gwangcheon Police Center and Gyeongsin Girls' High School, which means you have to walk quite a bit from the bus stop.
If I had just taken an express bus to Yusuk Hair, I would have just walked instead.
