I came across this today and thought it was a really great idea. One I had never seen before. I grew up along a river and there was always debris along the shores, stuck in brush piles etc. I always thought that in a survival situation, scavenging would provide a treasure trove of useful items. Like empty plastic bottles etc. that could be used for survival purposes. So I thought I would start this thread for simple, field expedient, improvised items that can be used to survive. No store bought hiker stoves, backpacking tents, space blankets etc. Just everyday things you can pick up and scavenge from nature or from mans refuse.
