Has anyone heard of or attended "No Lights No Lycra" event? It is an event where people pay a small entrance fee to enter a big hall with dimmed lights and dance, dance, dance to their heart's content. No grog, no socialising (discussion is apparently actually discouraged), nobody checking out your moves (hence dimmed lights) - the aim is to play and exercise and express oneself moving in any way one wishes. Like awkward dancing when one is at home alone!
I haven't been to one but am dying to attend! Showing how cool and hip and oh so up to latest crazes I am (NOT!), I only heard about this this weekend, although it has been going on since 2009.
