I've been to two in the last few months. They're pretty regular occurrences because, as I found out tonight, the Dallas/Fort Worth area is the #2 market for Laphroaig in the U.S.

The best thing to do is to join the Friends of Laphroaig and subscribe to the email notifications. This event was for FoL members only (no non-FoL guests) and filled up pretty quickly.
