It's been said before many times and I'm just saying it again!
this book is fantastic,
if you've considered Bivying (bivy bag)read this before, and after you will love it!
there are many many anacdotes that will amuse teach and give you courage when you need it the most!
the funny thing for me is i've been to several of the bivy sites he mentions!
Here's a link to the book/publisher!
