[PRCo] How can I join your group?

[robert simpson]

Having been a former Pittsburgher and a frequent rider of the streetcars, I have an interest in them.  
   
  How may I join your group.
   
  Was also a great fan of Rege Cordic and well remember some of his skits on the 77/54 - the "improper fraction"!
   
  I now reside in Vacaville, CA, but do visit Pittsburgh every year or so.  Miss the streetcars.
