I created a public Slack group for coordinating carpools to and from the outlying hotels. Use this link to get an auto invite: http://genconcarpool.herokuapp.com
I'm at the Hilton Garden Inn Indy Airport and was planning on taking Lyft or Uber but unfortunately there is no Lyft Line and no UberPOOL in Indy. There must be other folks at the hotels near the airport so I thought it might be cool to try to use Slack to coordinate this. If you like the idea, please spread the word.
