In my hurry to post results, I neglected to give the name of the handler and dog that were the highest scoring Labrador in the obedience trial. From the Open B class with a score of 196, they are:
Dunn's Marsh Caleb of Waltona, UD RE by Ch. Winnie's Block Buster, MH - Ch. Dunn's Marsh Legend in Her Own Time, CD TD RE. Ow: Lew & Susan Jenkins
My apologies for missing this result the first time around and congratulations on your win.
