That would be a tough one to answer accurately. There are so many clubs in CA these days that i think the number would vary greatly. Plus there is the 'security' issue where people probably don't discuss this with others, or at least the people who really know. I suppose some caregivers that provide surplus to the clubs may have an idea. Wish i had more info for you.
As far as as the recession hurting business, i am a firm believer that when most herbheads are slashing their spending, the medicine is the last on the list to get cut:thumbsup:
