There's now an open call for correspondents for the Urban Sketchers Symposium Buenos Aires 2024 which will happen from 9 - 12 October 2024.
I have been fortunate and happy to be the video correspondent for several USk Symposiums over the years but this year I am very unlikely to apply. The flight time from Singapore to Argentina is 36 hours and that doesn't even include travel time to the symposium location.
