flyinflyout is a great site for us in the mining industry - peripetic souls we are!

nice to be able to have a way to let industry friends know where 

we are, where we will soon be and where we are no longer! Nothing is 

more annoying that finding out someone important has been in the 

same place and neither of you knew - until after the event! -
