I stopped following Doug on social media a while back but just now did a bit of stalking - he posted on FB on July 13 that “Quantum is ramping up for a big fall season. He scored a 32 in the 5* test B on Sunday at the Carolina Horse Park and #jumped around the 1.35m today like a champion at [TIEC].”
Sure sounds like he was aiming Quantum for Pratoni at that time and right now is still showing entered in the 4*S at Great Meadow.
