You had to see two ladies to ring out the old and bring in the new.  Here's your guideline

1.  One has to be someone you have seen before to ring out the old year.

2.  The other, someone who you have not yet seen.  Thus the new.

Just know that you can't play with the new friend until after midnight.  Of course, there is nothing to prevent playing with the old friend after midnight.

My Choices (originally on the Florida board):

Old - Erotic Eve since she is so wonderful and I always have fun and enjoy my time with her.  

New - Sindie who I have been hoping to see and I hear she plays well with Eve.  Nothing like bringing in the year with a bang.

Of course, I could also come up with many other combinations.

For Philly, it would have to be Jade & Sloane.
