2POD

Picked up 2 packs of 2011 Opening Day, still hunting for some of the inserts, I'd really like to finish the Presidential insert set an the Mascots:

nothing new on the inserts side of things (I have both of those in the scan), but there is a nice blue border parallel of Ervin Santana. Oh well, we'll keep trying here and there...

here are the inserts I still need, though I'm not to worried about finishing the Topps Town or Celebrations:
