been hunting walkin areas for well over 12 years or so, one spot we frequent is a timber hole that is about a mile walk on levees and about a 500 yard walk in flooded timber. It feels like a Nazi Death march on the way in, and you want to just stop and give up the hope of survival on the way out, but its an epic spot. Packing light is key, we usually bring about 1-2 dozen decoys, 2 spinners, and our gear bags. We have a set of decoys we use just for spots like this. Put as light of weights on the decoys as possible. We have actually drilled out most of the keels and taken the sand out so they are water keels, to save on weight. I would try to rig up a cart to help carry everything in, that will save you a lot. I would also suggest not wearing your waders on the march, that helps way more than you would think.
