Robbie,
I don't think a day goes by where I don't think about you and Iberia. I still remember reading the updates from the vet's office like it was yesterday. I think I can speak for all of us when I say that heartbroken we all were when he didn't make it. Having said that, I'm sure that, more than anything, he'd want you to be happy and to stop beating yourself up over that awful night. After such a long period of time where he and Frank were getting along, there was no no way in the world you ever could ever have predicted those events. You did all you could and you gave both Iberia and Frank so much love.
We all miss Iberia and I'm sure that he and Loca are hanging out together at the Bridge.
Much love from Phoenix and I
