JoesKayak is correct re the Fearsome Foursome.  #1 of the FF is the 4’ right angle ledge – the first drop you come to downstream from the current put-in for running laps.

More FITW trivia for those of you somewhat new to the run…  The old put-in for running laps used to be upstream a bit, just above a great boof ledge that was originally named Limbo for a log limbo that was required in the lead-in.  In the River’s Tab of PP, this drop is now called Slot Wedge Ledge.  From this access you could either do a very aesthetic seal launch into the champagne pool above Limbo (SWL), or walk a short ways upstream to run a fantastic drop called “Slot Drop” (not to be confused with Slot Wedge Ledge…).  Slot Drop was one of the more challenging drops on the normal lap run.  It and Limbo (SWL) provided the two most classic boofs on the entire run.  Unfortunately, both changed for the worse, and (most) people started putting in downstream at the now current put-in.  Further upstream, between Slot Drop and FITW proper are two big drops.  The upper one is Double Undercut – a corkscrewing plunge into a narrow “pool” with a double undercut.  The lower is a fairly straight forward 8-10’ ledge drop that was more often than not blocked by wood.  Back in the early days when running FITW started with running the actual FITW drop (no bullet laps back then…), these two big drops between FITW and Slot were usually portaged.  You’d run FITW, boat through the little zigzag slot canyon below (really cool), and take out RR before Double Undercut.  On the portage you walked past remnants of an old cabin in the woods, which almost certainly predated I-90, and put back in above Slot. 

Also, Fisherman’s wasn’t named for “fishing” swimmers out of the hole with throw ropes.  Rather, it was named for two fishermen (young guy and gal fishing from the left wall) who were quite startled when kayakers ran the drop unbeknownst to them and plunged into the pool where they were fishing. 

Now why are we talking FITW in November?!
