Hi, I’m Karen, one of the hostesses for the event. We thought of that early on (the very first one, actually), and part of the admission to get in is a canned good/money donation for The Alameda County Food Bank. We have raised thousands of dollars for them over the years! However, this year we will be redirecting the donations to the Sonoma and Napa County Food Banks as they are supplying sustenance to the fire victims in these counties, as they are affecting so many and personally for many who attend.
Also, believe it or not, the food DOES get eaten and there is very little waste. Some of the dishes are actually quite tasty, even if they look inedible.
Thank you for bringing up a very important point, and one that has been addressed since the advent of the Potlucks. We have fun, but are incredibly conscientious as well.
