I can see that one of my replies did not post...
Anyway, GregT and g-man, thanks so much for this encouragement. I am a member of several "wine" meetups and, based on your suggestions, I asked some of my fellow members if they would be interested in doing a more formal tasting, rather than just the restaurant flights that we normally do. I got a little bit of interest so now I just have to figure out how to organize it (and get people to actually commit).
Anyway, thanks for the encouragement. I am already through Class #5 and looking forward to continuing to increase my knowledge of wine.
