over the last few months, after reading this and other forums, I've changed my thinking about the "packaging" of my car supplies.. my 72hour kit was really too heavy for an old guy to lug very far, and was missing several important items for trekking in sub tropical Florida...so I broke it down to a get home bag and removed the heavier 72hour supplies (Swiss volcano stove and Sterno, machete, extra food/water) and store them in a different bag... I added a second pair of New Balance shoes and more socks, a high tech moisture wicking pair in addition to thicker wool pair, couple of feet of duct tape to pre tape feet to prevent hot spots..medicated powder for chafing...extra long sleeved nylon cape back shirt, towel...replaced the canned tuna and ramen with foil tuna pouch and instant mashed potatoes...repackaged some GatorAid mix for EGR...I kept the nylon coated poncho and full sized mosquito netting,boonie hat+netting, SRK and Vic multi tool, topo compass, Ranger beads, Garmin Nuvi 500 has topo maps loaded, LED headlamp and task light... changed out the water bottle to a Sawyer filter bottle (pack has a 2 liter bladder) plus stainless cup, and aluminum bottle from Swiss set.. kept the FAK... and dropped the meals to two days...converted a clothes rack to walking stick.... GoreTex and fleece jackets always in car..umbrella...
