CAFE BRIDGE
It's quite a good way for people to try out duplicate for the first time in a friendly environment without very little knowledge of Duplicate.
It's also a way of keeping active and getting some fresh air, as well as potentially seeing a new place and visiting some pleasant cafes and restaurants.
It's usually fundraising which is a bonus.
