What’s knotfest like?

I just came home from knotfest last night… sorta. I’m too young to attend, so i hung around the area that of knotfest sydney last night just to listen in. I enjoyed that so much that even when I am old enough i’d even consider saving myself that 200 bucks and just listening in from outside.

Could anybody who’s been to knotfest tell me a bit of what it’s like and if it’s worth going?
