Kevin Stone, damn good player and nice guy, hosts a quarterly tournament on Saturdays in his home arcade.  I think he is up to 14 players now.  The competition is always good and I have heard it is always a fun time too with some very late night pinball.  Info is here and here.  

Last year, Kevin hosted the Virginia IFPA state championship playoffs so this is a good chance to get some time in and learn his machines.
