Well, first off make sure you get a GOOD breakfast before heading out if possible. Pancakes, oatmeal, eggs, and toast. Something that is going to fill you up and stick with you during the morning. In my pack I usually have a Deli sandwich I pick up on the way to the spot, a candy bar, a Gatorade, and a canteen of water.

On a side note, I find it funny that people are mentioning foods that will have a distinct smell. I hope those of you who mentioned candy bars and jerky didn't spend hundreds of dollars on Scent Lok, what a waste!
