On my day trips,I get up at 3:00 in the morning. Have breakfast at a 24Hr restaurant,bacon sausage ham egg combo, with pancakes toast (rye) on the side.Than I am on my way to Tim Hortons where I grab my thermos of coffee and a sub,(for my lunch ). I snack on peanuts and raisons and jerky (wild game) throughout the day .I drink lots of fluids (Gaterade or Powerade) through a water pack that is strapped to my back while I hike.In the back of my truck there is always a 18gal bottle of fresh drinking water carried along for these hunting trips.
On my overnight trips and 10 day exibitions I pack differently.
Freezdried soups and vegtables,Powdered drink mixes(gaterade,powerade) and peanuts jerky and raisons just to name a few things fresh water.
