Exciting recovery. Unfortunate loss on whatever was in the center. Think I would have left that hole exposed and come back with buckets or something. Good lesson for us all to maybe leave the ring alone until you get home. I know I’d have done what you did but maybe shouldn’t 🤷🏻♂️
Idea that’s probably dumb: bring a cordless shop vac back if you know where the hole was and vacuum around that area. Then search that?
