> The only downside is that someone has to take notes, which can be hard while walking, unless you can remember everything.

For some reason, walking meetings tend to work like a memory palace for me.

Though I walk down a pretty specific set of landmarks and write notes afterwards, which is usually ordered by the walk trail landmarks & a follow-up would usually not need a set of notes either.

There was a time when the smokers used to be the ones to do this as a matter of habit - these days it is much healthier to do walk-talks.
