Apologies accepted David - damn, and I was getting all geared up
for writing a sarcastic rejoinder :-)

Of course, if I'd said what you first thought, that IS way too
much salt.  But I think people stress way too much about salt
these days.  My understanding (and hopefully any knowledgebale
medical personnel will correct me if necessary) is that 1. salt
does not CAUSE hypertension, and 2. even for a significant fraction
of hypertensive people, salt reduction doesn't help reduce BP.

Anyhow, it's a bit of a peeve for me, because when people bring
this modern fad that salt (or sugar) is poison into places like the
Grand Canyon (or decide their hike would be a good time to go on
a diet) bad things happen.   Don't get me started on the time my
friend said she'd bring a bunch of this great trailmix she'd
found (for our GC hike), and it had NO SALT - arggh !   I've
never had such an intense salt-craving in my life ...
