So you have big glass, a new 3 pound digital body, 2 tripods, two heavy tripod heads, a couple of light devices, 2 reflectors, maybe a small blind, some lunch, binoculars and a bottle of water. You are 2 miles from your photo site at the trail head. What about a sherpa ??
See my Sherpa page and see if it works for you. http://home.earthlink.net/~mr1634/
