Well, believe it or not, I am. I found the site meetup.com and have started looking at some of the local groups. I've signed up for a ballroom dance this Saturday. I'm also looking into a sushi night tomorrow (I'm asking the coordinator if the location is a 21-or-older-only establishment first).
Next week I'll probably initiate contact with someone from the Racquetball interest list about playing a round or something.
