As I'm from the UK I have 868MHz nodes, so anywhere I go in Europe there's a good chance of picking up a mesh. I usually seek out a sightseeing spot like a tall building for the line-of-sight range.

Tall buildings are good but balloons are better. Back in the UK when someone had a balloon up over the English Channel, it got me connected all the way over to the Netherlands.

Maybe we could have a Nostr balloon node at some point!
