OK I’m in. Will generate a slew of letters today, make a record of who I sent them to, and if I get a response then will report it here.
They list mailing addresses and phone numbers. In addition they show maps of their districts that you PA Freepers can check if they represent you. I didn't see emails listed but I am sure a bit of research can find those.
Again, and I can't emphasized this enough, if you LIVE in their districts then a well typed snail mail is incredibly POWERFUL. Be sure to include your return address and phone and email contact in the letters. Also if you are rusty on sending such letters, check the Web for the proper format.
Phone numbers and email provided but not snail mail addresses. However, I think the latter can be found. If you find them please post here.
