It's not far from North Hollywood...
I'm 10 minutes or so from Eco-Safe's NH office and 20-25 from Valencia. I tried to schedule a time to stop by the NH office in the past, first with Michael (who was very open to it - I just couldn't manage it based on my work situation and they didn't want anyone to just show up. Always needed to schedule you're appt) and then with Paul Doucette (who gave me the run around).
Anyway, I was never under the impression that they would keep much inventory, if any, at the office. And, if they get a large order (I'm not sure what constitutes "large") Stoll would knock it out.
But, Ozone would know better than I would on all fronts.
