It was decreed some time ago that the ER was out of bounds to the lady passengers due to the secret machinery and other things located there.
How is it that ES has emerged from the dark and is swanning around with a group of ladies?
I now see that the ladies are enjoying the sights only to be seen in the Engine Room (with Tmac's specific approval apparently). Don't know what they expect to see down here as the only unusual sights that I have seen are short skirts climbing steel ladders.
