Usually just eat a bunch right before I leave and just drink water at every spring I come to, ever once in a while I might get get lucky and find an apple tree around old homeplaces on the mountaintops.
i like to take a sandwich bottles of water 3/4 frozzen then top off with water so its nice n cold all day i carry these in a backpack which also keeps me cool n some venny jerky n most important a bag of pepermint lifesavers
I drink out of the creeks and springs and I usually take a pack of crackers in case I get starvin'. I keep a few stems of the seng to chew on. Seems like I want to take a nap if eat to much in the woods. When I get home I usually eat like a horse.
Since I usually stay from daylight to dark and I cover a lot of ground I require a lot of calories. Most days I fry some bologna and eggs for a sandwich. I also take a peanut and jelly sandwich and a ripe tomato from the garden. 2 liters of water.
1) A jar of peanut butter. A few bites really go a long ways. Quite filling, since it has a good balance of protein, carbs, and fats. I used to have a difficult time eating peanut butter without something like jelly or jam, but I'm quite used to it. My main rule is to make sure I have a drink ready to go. I don't like stopping for long, so when I do, I tend to scarf it down. Peanut butter doesn't like to be scarfed.
2) Granola bars or cereal bars. Not quite as beneficial as peanut butter, but pretty good for easy food.
3) 1 gallon of liquid. Usually, 1 quart of tea, 1 quart of Gatorade, and 2 quarts of water. I reuse the 1 quart sized Gatorade bottles. I have a couple of springs that I'm not scared to drink out of, so when I'm going there, I don't take as much.
If there is a chance I might end up spending the night in the woods, I'll take extra dry Gatorade in Ziploc bags, extra granola bars, and I'll make sure that the jar of peanut butter was full before I left.
Sometimes, I'll take something like Honey Nut Cheerios to mix in with my peanut butter. I am trying to tell my brain that it is something completely different, but I think it knows better.
On occasion, I do take Vienna sausages, but then I have to take extras. I like them more than the peanut butter, but they just don't satisfy my hunger.
