I started with rock climbing but gradually shifted towards caving and canyoneering, partly because I started kind of old and knew I'd never be able to take on some real rock climbing challenges, but a great deal of it is I never really enjoyed the spiritual bro dude attitude of the community. Cavers tend to be an assortment of older nerds and scientists.
Serious canyoneers tend to be wilderness experts and nature lovers with some sort of deathwish.
