Welcome to Hive @featheredfriend! Check out the "#steemskate" community (probably changing names soon.) Not sure if there's any dedicated community for surfing yet. I also skate — just picked it up a few months ago so very basic but enjoying cruising around :-) Also #photocircle and #naturalmedicine might be good places/tags to use for your nature photography!
Btw, just a technical thing — only the first 5 tags on your post will sort it in categories... so this isn't showing up under #introduceyourself. Hope some people lay eyes on it nonetheless! Cheers.
Thanks for telling me, I'll re-post tomorrow. Thanks for the link for steemskate!
