Mad!

We went away in the caravan this weekend.  On the way home today, we stopped at Lake Rotoiti and had lunch.  A 'Kiwi Experience' bus arrived, full of young adults in their 20's, who proceeded to getting into their swimwear, and jumping into the lake.  The outside temperature was 15 degrees;  the water temperature would have been a lot cooler than that.  They were mad.  But I suppose that's what you do when you are young.
