They are everywhere this year! There was a second KetoFest (not as scientific, more social) in New London, CT last month. The videos from Science Sunday should be posted soon.

I know two in Washington DC, one in Houston, etc.
Two open FB pages you can check for events are HealClinic and Adapt Your Life. https://www.facebook.com/pg/AdaptYo...f=page_internal
Get on the LowCarbUSA email list..there's usually one in FL in January.
Then there are small groups popping up everywhere, not big name speakers but folks getting together to share information, aka "Meat-Ups"
