This is one of two events put on by the Home Orchard Society (
http://www.homeorchardsociety.org/events/). I have been wanting to go for several years, I was finally able to make it there today.
They had an amazing variety of fruit to see and taste - I think they said they had over 1,000 varieties! I would guess that they had about 400 varieties of apples, several hundred varieties of grapes, and several hundred varieties of pears. Also present were kiwi, quince, medlar, and a table of unusual fruit and berries from
http://onegreenworld.com/. OGW had some plants for sale, and HOS had a few potted plants for sale also. But the "main event" is ordering apples from HOS. After tasting the 400 varieties of apples, you can take your list of favorites to the ordering table, and order your favorite apple grafted onto a rootstock of your choice, for $12 each. Over the winter they will build your trees and you pick them up at their Scion Exchange in the spring.
If you like fruit, especially apples, grapes, and pears, you should plan to attend next year.
