Hobart Australia tradition

I took a walking tour of Hobart and learned that each year on the day after their longest night ( around June 20) they do a mass skinny dip. Last year they anticipated 1000 people, but had 1200 show up. They had ordered towels but did not have enough so some had to share. The guide added sharing towels is a good way to get to know someone. I told him I want to be here someday for it and told him about my friend and I being the hot air balloon pilot's first people to get naked while floating above the Yarra Valley with him.
