Welcome to the TPWD series which stands for Tom Plays With Ducks. Tom, aka Electric Water Boy, gave me the idea for the name since he had worked for TPWD, Texas Parks and Wildlife Department, and I currently do. This is a geo-art series containing 24 puzzle caches and 1 wherigo cache. The series has 3 main categories: wildlife, state parks in Texas and lakes in Texas. TEN of the puzzle caches are GADGET caches, all found in AMMO CANS. The difficulty rating is higher on the gadgets because you have to solve the puzzle and actual gadget cache. You must sign all logs to get credit for the cache. Good luck!

The Puzzle
In Texas, there are 3 main types of waterfowl: diving ducks, dabbling ducks, and geese. In general, diving ducks prefer perennial bodies of water, like lakes, stock tanks, backwater river areas, open bays and marshes having a constant supply of water. In contrast, dabbling ducks show greater favor to shallower and more seasonal water supplies.
GADGET: Big Box-magnets and written number is the key. Little Box-count them.
waterfowl is keyword
