Our 6 and 1/4 anniversary (25th, we married on Feb. 29) was spent on Whidbey Island. The birds weren't overwhelming but the species were nice. Alas, the weekend was shorted by the wife breaking her leg by slipping while going down to the beach on the west beach at Deception Pass, but fortunately that was Saturday so we had two reasonable days of goofing off and some birding Thursday and Friday. Weather was partly cloudy, not too windy, 40+.

we consider this a tolerable list.
