Which sub were you thinking about specifically out of curiosity?
I created it to replace the /r/backcountry subreddit which was also skiing and snowborading. Perhaps it makes sense to broaden the scope a bit since the lemmy community is small. I could reasonably moderate hiking and camping stuff as well.
I will make a post over there asking people what they are interested in.
