Q: [header] How to start a bonfire [title] Clear a space for your fire pit. [step] Your fire pit should be constructed on bare dirt. If you are at a location that has a designated fire pit area (like a campsite), you should build your fire there. <sep> (A) Make sure that you have enough room to both build your fire and the space being reserved for the fire, and that there is enough water to extinguish your fire. [substeps] Ideally, the fire pit will be cleared by dirt, so the build-up of water will be less intense. (B) Most people build their fires under trees, bushes, or other sources of light, but they will also build a bonfire outside on trails, sidewalks, and between branches. Sometimes there will even be a ramp or ladder located at the bottom of the fireplace pile. (C) Otherwise, pack rocks, twigs, or rocks into the pit and fuel it up. [substeps] Logs and logs are the best to build your fire pit in. (D) If you are in a more uninhabited area, you should clear away any flammable woodland debris extending at least 8 feet away, and build your bonfire there. [substeps] Make sure your fire pit is not directly under any tree branches or hanging plants.
