David, I too was at Ernesto's presentation & was impressed not only by him
but by the group as a whole. I have to thank Sue Haffner for inviting me.
It was nice to hear Ernesto recommend the PBS wiki & show some of South
Africa's remarkable bulb plants/flowers. I got the impression that many of
those present were bulb fans as well.
