wango,
they only move in close at certain times not all year round , very nasty! it only happens in tropical australia queensland and the top end lots of beaches close due to them many tourist pay big bucks to have a great day at the beach only to find that you cant swim!
ohhhhhhhh well crocks could be worse
. i live in the south so we dont have the above problems only crap weather and work!
