For juvenile consignor David Scanlon, this sale season is about continuity. Scanlon will be bringing about 70 juveniles to auction, but this time he'll be doing it without his father. Robert "Bobby" Scanlon, a fixture on the 2-year-old auction scene since the early 1990's, died of cancer at the age of 57 last October, just as many of this crop of sales candidates were arriving at his training center in Florida as yearlings.
