These guys are a bunch of goons that talk about polo sometimes. Mostly just say stupid shit and talk about getting lit. Sometimes funny. Been downloading and listening while on the road and they keep me awake.

Midwestern dudes that talk about polo and the midwest. A lot more "organized" and focused on polo. Bike nerd talk, but still pretty good.
Enjoy!
