Haven't heard of unconf? 

Also I think as nostr grows, there will hopefully be more opportunity to meetup in closer areas. The only meetup in the US here I've been close to was nostr valley and I couldn't make it happen. Not very many young nostr "enthusiasts" yet, but I'm hoping there will be. Flight's and hotels are also a bit spendy for me these days. 

Myself and I think many others would be happy to just chat, few brews and have a good time.
