DLB, I've been in sports bars and so forth without drinking before but it was usually because I had already drank too much elsewhere or was half sick from drinking the previous night. My wife's work Christmas party this year was at a kind of pub restaurant and I was not bashful about sampling the craft choices they had on draft. I don't anticipate that being as much of a challenge though as some other situations.
Just found out that our drinking friends are having a birthday party in a couple of weeks. This will be a bigger challenge but I'm not so intimidated by it anymore.
