Submitted to The Union Mardie Caldwell, owner of the Foothills Event Center in Grass Valley, said phone calls began pouring in from community members expressing sympathy and best wishes after she announced earlier this week that the event center will be transferred to new owners this summer. The space at 400 Idaho Maryland Drive in Grass Valley will no longer be an event center. Caldwell said the center would have no issue going forward with clients’ events through July, and that other upcoming clients had been contacted and offered refunds — or, in the case of some of the clients planning weddings at the center, shifted their plans to Caldwell’s outdoor venue, Rough & Ready Vineyards.
