You are indeed getting lots of good info.

I would caution on one thing though, which is mosquitos!  (And
gnats or noseeums, flys, and probably something I've forgotten
about.)

One post said that morning frosts late in the year will kill the
mosquitos.  That is *emphatically* not true.  What you want to
be very leery of is assuming that because it is cool or because
there is a breeze *at* *the* *moment*, that you don't need to
have bug dope with you.  Take a hike early in the morning down a
path that is into the wind, and you may be fine with no bug dope
along.  Of course by 1PM when you turn around to come back it is
warm and that slight breeze is now at your back.  You might
literally be eaten alive by mosquitos!  The 4 mph breeze will
mean you cannot walk away from the cloud that forms as you walk.
They follow the carbon dioxide trail that you leave...

Another post correctly mentioned that DEET can eat plastics, but
I'm not convinced that avoiding it entirely is a good idea.  It
is by far the best mosquito repellent available.  Just be aware
that having it on your hands means you do *not* want to handle
plastics, which include cameras and perhaps your eye glasses
too!  In addition, you probably don't want DEET on your skin
*anywhere*!  Even people who do not have sensitive skin should
probably avoid direct application to skin.

Instead, a little DEET on your hair and on your clothing can go
a long ways.  Of course that assumes you are not extremely
sensitive the mosquitos (and can tolerate a few bites now an
then), and that you are not some place where mosquitos are
extremely thick.  In those cases all the protection that can be
had is essential, and DEET is just about the only repellent that
works well enough to provide it.

One of the B vitamins is good (I can never remember which it is),
and do *not* wear green or medium to dark shades of blue or brown,
as those colors attract mosquitos too.

Be prepared, even if it does not appear to be necessary.
