DIY Sand and Rock Box by FSPDT. Gdjk -> made this with toilet rolls (aka tunnels) and moon sand instead of play sand. My son loved playing with it. The moon sand cleans up nicely indoors but play sand will be easier to play with when using the small cars.
Install gravel, stone, or wood-chip barriers along the edges of stone walls, ornamental gardens, and woodlot perimeters. Any border created between your home and the environments where ticks thrive will contribute to your family's well-being. Snakes too?
