looking for an enlightening, spiritual, safe, and challenging Voyage.... I need some pointers, I am hiking into the deep delta junction of Alaska and going to park my truck, hike in about 20 miles along the river and make camp for about three days, I am planning on doing a superfood cleanse and just focusing on my art and music... I need some suggestions to pack for superfoods for my cleanse... pleanty of water, and I have enough AK camp gear, guitar, and notebooks... what else am I forgetting on my adventure... (my .45 is also coming)

Thanks!!!
