Never have. The WotC locator tool is useless - it shows over a dozen stores in my area that participate in Adventurer's League, but most of them actually don't. When I call to check, half of them haven't heard of it before, and the other half said they used to, but stopped a year ago or more. There is one store in the next town over that has an active running game, but it's a 45 minute drive away, and happens right in the middle of my workday. My normal gaming group once tried to run a home AL game, but we found the restrictions too restricting for no benefit.
