The other thing that makes them stand out is the 66 foot soda bottle outside, complete with a straw. If you are lucky enough to be there at night, it lights up with 'Time Square quality LED lighting'.
So even if it is a bit out of your way, I suggest planning to stop for gas and a soda at POPS if you are ever in the area.
You can check out more about POPS here.
And if you are overwhelemed by the choices, go for their signature root beer (made in Arcadia, OK) or the Peach Nehi. Y-U-M!
