Maybe it's not quite warm enough to pitch a tent in the backyard yet, but that's OK. You can make your own in the living room. Lay a blanket on the floor, put a chair on three different sides in a triangular shape, then drape bed sheets over the chair backs. Add blankets or scarves to give it a little flair. Break out the sleeping bags, make s'mores in the microwave before bed, and tell ghost stories. Give the kids flashlights or lanterns to find the bathroom in the night, and wake them up to "breakfast-in-tent."
