I admit, I was a bit turned off the by the kandi thing in the beginning =)
Now, I love it- it's a conversation starter, and it's a ritual, as silly as it may seem to have a special handshake and hand over some cheap neon jewelry. I love what PLUR stands for, and I think that especially important to have a mantra of community and compassion when we're a huge group of people, potentially under the influence and in a vulnerable state. In general, EDM culture looks out for eachother. The more kandi I see at a club/event when I walk it, the more hugs I get, and the more friendships are forced typically.
