Gann-Frankel Appear to Split..

I have heard a couple of rumblings about Cali trainers wanting to move their horses east to run on dirt. On the flipside, the owners are wanting them to stay in Cali to run on PolyTrack. I wonder if this was a deal breaker between the two or if it was just an ingredient to the overall split. It is sad to see these two split because they had so much success. I wish both parties continued success.
