Another neat little tid-bit, is at the end of the article preceding the section on Pattern Blinds with Diversions.
It goes a little something like this; "By the time a dog runs his fifth or sixth blind drill, he is often lining the blinds - that is, lining directly to the blind without any casts. At this point, you should quit running blind drills........"
I wonder why that is? Oh yeah, he goes on to say why, in the same sentence.
"..........because, you don't want the dog to become too accustomed to going back to a blind he's just been to."
"You should continue handling training with diversion work on the pattern blind field."
