no matter how much you think you know about the natural northern world, specifically flora and fauna, this book knows more. sure, we all know that a spider's webbing can be twice as strong as steel for its size but did you know that spiders can custom blend their webbing for different tasks? stretchy, sticky, tough..umm...buoyant..er ,well, other qualities relevant to spiders. its like a more basic, easier to understand kinda string theory.. sorry, slipping off topic here. this book is great, breezily written, funny even. get it, put it in the bathroom and in just 30 mins a day.. no,wait, that's the learning company..you will be able to amaze and confound all your friends from wood chucks to marine biologists with your arcane knowledge of the great outdoors. well, hey, its working that way for me.
