The Winter Summit participants have had this for a few weeks now, and no one has screamed about anything being inaccurate, misleading, or too revealing, so it's time to share the latest Summit report more widely.

Hey team,

I'll go look to see who's in the MEP group, but does anyone in this circle have a northern California design engineer for institutional work that they'd particularly recommend?

We just heard from one of our more progressive clients that they are pulling Mohawk from their shelves and are no longer allowing it on their projects. Apparently there are some chemical ingredients they objected to, but more importantly the manufacturer "lied" to the client about the content. Does anyone have an idea what this might be about?...
