I always have one tucked in a corner of my pack or daybag somewhere, just
in case. The following is quoted from Andy Woodward, who used to be a
frequent contributor to several groups I belong to, including rec.
motorcycles and the Primitive Skills Group (this quote is surprisingly
readable; Andy was well known for frequent typos). Haven't heard from him
since he finished a contract job and lost his university e-mail a couple of
years ago. Anyway, the only improvement I can think of to Andy's
description is the addition of a bit of foam or something to sit/crouch on
to reduce heat loss to the cold ground/snow.
