Hadley Creek Golf Learning Center (#27)
Though this park primarily consists of a golf course and driving range, there are some undeveloped parts such as the forest that houses this cache and the adjacent pond where you can put a line in the water. Do NOT attempt this cache in the summer unless you are covering up every inch of your skin. It is completely surrounded by nettles on all sides. I also got a wood tick from the 20-foot "bushwhack".
Cobalt (#27)
Cobalt is a chemical element with the symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.
