The Celiac Disease Foundation's 20th Anniversary Annual Education Conference and Food Faire (try saying that 10 times fast) is scheduled for May 15th, 2010. If memory serves me correctly, that is a Saturday.
Location: Los Angeles Marriott Downtown
Details available at: Celiac Disease Foundation
I am more interested in the Food Faire than the Conference...even though I don't tend to gravitate to events or stores with supernumerary letters (like Ye Olde Goodee Shoppe).
