Phew! We have a clear winner. With one vote each we have paul @9, fiery @11, and spike @42; with two votes, mathprof @12, rossim @4, fiery @36, and spike @31/33; with four votes, spike @30 with:
Force winter wheat to germinate without nitrogen (10)
Note that spike really nailed it this week with seven out of fifteen votes.
I was surprised that there was only one reference to the scandal, from mathprof (I call my document shredder the Hillary).

I recently mentioned to dorrien how much my wife and I enjoyed hiking along some of the rivers that flow into Lake Superior, in the Upper Peninsula of Michigan, like the Black River (this one) and the Presque Isle- so many beautiful falls there! Quite the joyride, although you might want to turn the “music” off.
Thanks to all for some innovative clue-writing and nifty touches, like bigbad's misdirecting rafters.
