In addition to the electric socks that someone else suggested, a
backup O2 bottle is a wise idea. Mtn High used to sell them for about
$100. Buying or borrowing a Nonin or other oxymeter would also be a
good idea. How else do you know your O2 is working properly? Maybe the
cost could be shared with some others.


Just FYI, Soar Miden included the bailout bottle when I was there last
winter.
