an article in Tactical Knives by Jeff Randall tweaked my interest in this ETS forum...surviving the jungles of South America with only water, machete, poncho,and mosquito netting... my 72hr kit is built around a poncho, water filter bottle, and mosquito head net (w/boonie hat)....sitting on a 5gal bucket and leaning against a tree I don't make a readily identifiable silhouette..almost a ghillie suit for a city park, the disruptive pattern of the camo on the poncho is ideal if you can find minimal undergrowth and effective use of shadows..and is easily rolled or stowed in a pouch for discrete transport... conversely as an old retired guy, I could probably reverse my sleep pattern...find a nice sunny spot in the park or beach area... set up a folding camp chair and sleep in the cool morning or late afternoon...
