On my way to the Cosmic Flows 2025 Conference, that is going to be held at Tamborine Mountain near Brisbane, in Australia.
https://indico.global/event/12931/ #cosmicflows2025
This is my first conference in 5 years - last one was the AAS235 in Honolulu back in January 2020, before the Covid crisis...
