Attached, from Carl Bogdanoff, are 2 files:  the Winter Grape Bud Hardiness results and the Predicted Bud Hardiness chart for Early April.  The sampled hardiness levels were determined as average lethal temperature exotherms (LTE) measured on buds of several varieties by region collected on April 6th and 7th in the Okanagan Valley.  These are the final bud hardiness measurements for this winter.
