It all started with some digging in the SpaceX parking lot after Tesla CEO Elon Musk went public with his grand plans for underground travel. Now, that project has received multiple additional approvals and could eventually extend throughout Los Angeles.

Not long after the first mention of Musk's boring pursuits, he took to social media to tout government approval for another series of tunnels on the other side of the country. Many people questioned him and laughed it off since he didn't provide real specifics about the "government approval." However, Musk maintained that The Boring Company would begin work on a tunnel that could transport folks from New York to Washington DC in 29 minutes.

Despite doubts, the company began breaking ground a few months ago in Baltimore, Maryland for what appears to be that project. The popular CEO has become a self-proclaimed hat salesman to raise additional funds for these projects.
