Thet water purifier tip is a fine one. Those things are light, an' you can git dehydrated so easy, it doesn't make sense not to have one in yer pack or saddle bag. Used to be you could drink outta most the streams an' springs in my unit. Now all the yuppie backpackers an' too many outfitters an' horse campers make thet impossible. Water is the single most important thing to support life (assumin' you already got clothes on). Also, keepin' hydrated will make you hunt and feel better. I hate them powerbars but allays have a big snickers and some jerky with me.
