I have found that I have a much better experience if I fuel myself with decent food when camping. We will usually prepare some raw veggies and fruit ahead of time for snacks and meals. It is much better for keeping the energy up, does not bloat and bog you down like a fat steak, or smokies, hot dogs, hamburgers etc. It also allows brown-time to be less frequent - if you catch my drift. We also try and avoid the really sugary snacks. Nothing like crashing from a sugar buzz when it's your turn to split some wood
Don't get me wrong, we eat our share of bad food camping too, but we do bring along healthy stuff. We eat a lot of chicken and fish. Sometimes we will prepare a meal and take it with us for the first night so we can concentrate on setting up, or exploring or whatever instead of taking time out to whomp up a mess 'O vittles. More time for play.
