A while back I mentioned that you can no longer take an MTA bus to the Raven's home games from a park and ride.
Turns out the regulation is that if you take Federal money for your mass transit, you can't use that mass transit to compete with private companies (like charter buses). I'm sure the intent is to keep the MTA from sending city buses to Atlantic City, and to me, it makes sense.
So while it's a federal regulation, it's in place to keep states from using federal dollars to compete with private companies.
Solution: Stop taking the tax dollars of the citizens of Iowa and giving them to the State of Maryland for bus service.
Just a thought.
