The New Forks is in a 'No Burn'
season, which means no charcoal
and that's what dutch ovens use to cook with. So, you're off the hook on the DO cooking at the Walk with the Winds gathering.
Forest, where you're going, I would think canned food would be your best bet. Cans keep well without need of refrigeration; and, if kept out of sight, 'most' bears won't know what you've got hidden and won't go looking for them.
During a No Burn
season, propane stoves are okay; so, start with stove top cooking, heat-up type meals, like chili, stew, spaghetti and soups. They are always okay to camp with. As far as a peach cobbler, you can make something similar on the stove top. You just won't have a crisp brown crust on top; it'll be a dumpling style. ...Or, simply take a cake or cookies or brownies from home. They should keep in the distance that you're driving. I'd guess that you're only a 4 or 5 hour drive from the campground.
I'm finding that it costs some and/or requires effort to get properly "suited" up to cook with a dutch oven. Then, there's the extra weight and space it takes up.....
Take your time and think on it a while before you get into all the DO stuff and be certain that it's what you want to do. It's much easier to enjoy and "Oh" & "Ah" over someone else's DO creation and the compliments will feel like desserts to the DO cook's ears.
