The price of freedom is eternal vigilance.
And similar :-).
Alas I had to go to the airport and this post was 4 hours old when I
read it, so I thought "Oh no."
Actually, probably more like "OH! NO!!!"
Where is (I thought) the

             <FlameShieldsOn> instruction ? !!!!!!!!!!!!!!

Usually an utterly necessary prerequisite to such material in this context.

And I expected to find blood all over the ranks.

I read on with trepidation and some surprise.
I did find a modest amount of blood, almost a trivial amount, but it
seemed as far as I could tell, to come from Middlesex County, so its
loss  will almost certainly not be noticed, and it will almost
certainly have no effect whatsoever (more's, perhaps, the shame) so
all is weller (nothing to do with Copper group [tm]) than may have
been.

So, congratulations. Well ridden. Looked like a Class IV verging on V
on entry but, as is often the case, with suitable handling and
adequate disdain of bluster abs appearance, proved to be only a Class
I (Waves small; passages clear; no serious obstacles).

No that there was some good & useful Class III technical stuff in
there amongst the spray and eddies. Also some good Class II
contributed by lookers on and well wishers. Note for reference that
the V/I may be followed by a III tail in an attempt at redress - so
success in the V/I should be taken as modestly as it appears to have
been and the following III approached with due diligence. If note is
taken of " ... requiring expertise in maneuvering ... " you'll
probably do OK - you seem pretty competent at this so far.

V: Exceedingly difficult, long and violent rapids, following each
other almost without interruption; riverbed extremely obstructed; big
drops; violent current; very steep gradient; close study essential but
often difficult. Requires best person, boat, and outfit suited to the
situation. All possible precautions must be taken

III Waves numerous, high, irregular; rocks; eddies; rapids with
passages clear though narrow, requiring expertise in maneuvering;
scouting usually needed. Requires good operator and boat.
