Yellowstone / Teton Alternative Camping Recommendations

Since you have a TC, coming from the Tetons to Yellowstone there is a CG, I don't remember the name soon after you get into the Park that would suit you, no big rigs. Also near Flagg Ranch there is some primitive spots along the river.

In West I usually stay at Campfire Lodge and Resort, on the Madison. There are also some FS Cg's near by. Also in a pinch and depending where your heading there are several BLM CG's along the Madison. If you head toward Bozeman there a several FS CG's on that roadway.
