What are the popular hobbies for real estate investors?

[Anibal Mijangos]

I come from the blockchain world, where a lot of conventions and shows happen at venues with casinos. The top influencers and company executives in the industry would always be found around the poker table. Probably because of the somewhat gambling nature of the developing blockchain/crypto space. It got to the point that if someone wanted to network with them, they had to learn how to play poker well. 

Has anyone noticed something similar for real estate investors? I was thinking it would be golf. Or maybe even collections such as cars and watches.
