Hey UG.
LTNS. How goes?
Sounds like an old Tank & Wendy challenge, but I can't remember which one offhand... Sorry I don't have the time right now to go browsing through again, but if you check the archives for stories they've coauthored (under W or R for Wilson, Tank and Richards, Wendy) I think you'll find it.
EDIT: Okay, I had a bit more time than I thought. Just went through the archives. Was
this the story you were looking for?
