The one we just finished, A Community Affair, has been going on for over 30 years. I can't remember if they said '32nd' or '37th'... they kind of sound the same. I can't say enough about the helpful staff and the wonderful organizers! They made us feel welcome, they had lots of helpers there to wheel in your stuff or bring you chairs, and they had runners to deliver lunch orders and coffee, and even desserts in the afternoon!
The crowd was fair-to-middlin' as they used to say. I thought there were too many lulls but maybe that's how it goes when it's drizzly and cold. There were a lot of people who walked by our table, admired, and walked on.
...although it was crowded because our booth partner had big stuff, those are deco-mesh wreaths.
