FYI: Bouldering comp. is super fun and for all levels no matter you are doing it to compete to be the best or doing it for fun. Climbing comp. in general is v. different from other sports, where participants cheer for each other, share beta, etc. instead of wanting to run over each other.

Since it's in the States, you are recommended to buy some health insurance or else you might end up with a nose bleed and it costs you a few thousand dollars.

And the obvious safety/liability disclaimer: climbing is dangerous and participation could lead to death. You are recommended to seek legal advice before participation. Thank you.
