Here are three Steemizens and a couple Steemit T-shirts at the Exton Bitcoin Meetup. The topic was "Bitcoin for Beginners."
Good food and service from Pizzeria Uno, and a good bitcoin presentation by Joe Rosatto. Of course, I couldn't stop myself from mentioning Steem's million transactions per day. And we were surprised to meet someone else there who was talking up @eosio.
If you're in the area, they meet there at 7:00 pm on the 2nd Wednesday every month.
