Overall, I probably ate around the same amount; but the big difference was how much better the food tastes when you are camping out by a lake somewhere and cooking over the campfire. My folks always went camping, so I grew up enjoying those weekends spent out camping. The breakfasts that my mother cooked over the campfire first thing in the morning, are the breakfasts that I will always remember for the rest of my life !
We were always starving when we woke up, and the smell of coffee boiling in the coffee pot, and then bacon and eggs sizzling in the frying pan, were just the most awesome smells in the world. Even pancakes were good out there ! ! I have never been a pancake eater, but I would eat 3-4 of them with lots of butter and pancake syrup along with my breakfast, and enjoyed every bite.
When you are out in nature, and walking, swimming, or rowing the boat along, it is easy to wear off the calories that you ate, and have a great appetite for the next meal, and in the fresh air, the smell of cooking food is SO much more dynamic than it is when you are inside and cooking the same food.
