There is a wonderful forum with tons of info on all things in the
Whites called Views From The Top. Lots of really knowledgeable folks
there with endless advice.
Presi traverse certainly works in either direction; I'd prob start
from the north because the northern stuff seems to me to be a bit more
intense -- but people do it both ways.... There are some shuttles
available now if I recall correctly but there aren't many of them (or
weren't, last I checked) so the timing is tricky esp if you are doing
early/late starts and finishes.
I always love an excuse to carpool/split gas and go down there, as I
really can't justify the expense of going alone! Please feel free to
connect if you possibly want to attempt to coordinate -- I'd prob just
do other stuff solo while you-all do the hardcore stuff. If schedules
are compatible I would be into helping with shuttling or support or
whatever. Can fit three friendly passengers and gear in my car!
Peace!
