imagine, if you will, laying in a small bivy shelter (e.g. ID eVENT UniShelter) with no tarp overhead, and a violent T-storm rolls in. further imagine reading one of the Psalms describing the awesome power of God while this is occurring. humbling experience. puts many things in perspective - for me at least.
so, my luxury item is a small tiny print Bible, or at least a New Testament with Psalms and Proverbs also included.
dual use? well, at the risk of being called sacrilegious, and since i'm NOT a Bibliolator, in an emergency,...well...hmmm...i think that it's better left unsaid so as NOT to offend someone else. [just note that generally, not all of the pages in a bound book are containing the text of that book, though i might, personally, NOT limit myself to such. i know, real UL philosophy would dictate that these pages and the cover are removed b/f the trek begins, or, only the pages one intends to read should be carefully excised from the book and carried on the trek.]
