The chowhounds of the Bay area are hosting a hundred hound picnic in early October (see link) to benefit chowhound.com.
Is there local interest in having a similar event?
A quick rundown on how it works:
There is a fee per adult participant, each paying adult may bring one under-12 child.
each participating adult must bring one dish that feeds about 20, to represent something particularly delectable and regional or a family heirloom recipe.
In other words, it is a luxe potluck with an admission fee, to benefit a good cause.
