Good to hear from you HP. The problem with vet scratches, as you know, is that it is next to impossible to find out the reason. As just one example, my understanding is that a horse which ships is a vet scratch if the trainer has not complied with the new jurisdiction's requirements to run on lasix. I think that in some situations you can learn more from trainer scratches than you can from vet scratches. Two that come to mind are horses which have been scratched numerous times & 1sters which have been scratched by certain trainers in order to avoid an odds on daylight winner.
