To add to that: I've heard in the past that "DebConf is not the
place where everyone is keen to go into nature or engage in physical
activity". Let's not think like that. Obviously, not everyone will
join, and we do have people with limited ability. But if we give off
the impression that the day trip is only for sports freaks and
nature geeks, then we're ourselves cutting into attendance. Rather,
I think we must ensure an inclusive programme, and a default
expectation that everyone joins — and assume/communicate that in
everything we do.
