So do I and it's a 3000 square foot residential. The biggest money maker on the planet. I do some commercial work but if I had my druthers, every job I did would be a working couple or retiree with a 3K resi. Everyone seems to love the big commercial gigs, but the money is in the small ones. And for something that's gaining ground as you say.....I didn't hear about the gimmick till last week and when I did I chuckled and thought of the pet rock.
