I will live completely from my back pack for 4 days. No restrooms, no water, no electricity.You gonna be completely off grid? Or taking the pussy way to stop at sanitary facilities (like I probably would if the alternative would be to wash myself in alligator-water).
What are you gonna eat? Your backpack will be full I suppose.
A couple of spots on the property have old hand pump wells that I'll be treating for water to drink and bathe. Gotta dig my own latrine. For food I'll have beef jerky, peanut butter, tortillas, protein bars, tuna and Ramen noodles, some dried fruit. Instant coffee.
My bag should weigh around 30 lbs when I'm fully packed.
I also have some wet wipes
