Hi, Amy--I was reading along here, catching up, thinking, "She needs to hang out with some Girl Scouts to learn how to start a small campfire." Girl Scouts are big on small fires (my husband, Mr. Big Fire usually ends up doing our fires, though, darn it!) Maybe you could volunteer with a local troop and pick up some tips. One typical Girl Scout method is to gather some small dry twigs from the woods near your campsite, and a few dry leaves (not too many--they make a lot of smoke) and maybe crumple up a piece of paper or two and put them in the fire ring or pit with the paper on top. That's your tinder. Then arrange some bigger sticks in a teepee shape over the top. That's your kindling. Then light the paper with a match. Assuming it isn't windy, the paper will light the leaves and twigs, which will then light the sticks after awhile. When those are going good, add a couple of logs. It's good if one leans up against each other or you can do another teepee. Once the logs are going, poke them with a long stick every now and then to keep the fire active. Then, before you go to bed you can toss some water on it, so it's out for the night.
It isn't rocket science, but you will need matches for this experiment! Oh yes, and a lot of places are worried about the Emerald Ash Borer and so you would need to purchase logs near the campground. Usually there are places that sell bundles of logs or scraps of wood. Sometimes you can scrounge enough off the ground in the park, depending on how busy the park tends to be. Keep the wood covered with plastic if it's rainy. And if it's windy or the park has a no fires warning out, then obviously you wouldn't have a fire.
The fire is at least one third of the fun of camping, IMO!
And as for the potty--most tent campers don't feel they need that. Just take a big flashlight and go before you turn in for the night. We've never had one. The trek to the latrine is part of camping, IMO!
