We ran bees in California until 1989 when I came to Hawaii. WE had one case
of buckeyempoiisoning and that was in the coast range, San Benito County,
about 1940. We ran bees in the Sierras every year and found no effects from
buckeye. We assumed it was because when the buckkeye was producing so was the
Toyon and Manzanita. We also tried to find areas where there was not much
buckeye. I draw no lesson from these facts. Bears and skunks were more of a
problem in  the hills.
