I've been to many functions with hobby friends, such as restaurants, theater, symphony, motor-cross and other sporting events, shopping, strip clubs.....it's all good! I almost always give my real first name when I get out and about, because like the gents, there's always the possibility of running into people I know.
Disclaimer: Before some well intending gent asks, sorry....I don't barter BCD activities for the experience of a date that includes activities other than BCD.
