How To Find Awesome "Underground" Bus Lines 

 A similar concept without TSA trying to inspect your body and possessions, Wanderu is a great search engine for surface transport between two cities. 

 There are bus lines that you would previously only have access to 1.) Through being part of an isolated community, 2.) By word of mouth, 3.) By coming across a schedule passed out on a flyer, or 4.) Posted up on a sticker somewhere like the side of a building or a streetlight pole.  

 Wanderu taps into some of the college-town-to-suburban-mall-parking-lot bus lines, the Miami-to-Guadalajara-type bus lines that line the American south, or the extensive network of "Chinatown express" lines that, in abundant quantity, once formed a vast network across the northeast before they were targeted for termination by nanny state "do-gooders." Such do-gooders remind us why such bus lines are underground to begin with.
