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
Most waterfowl are migratory. As seasons change, waterfowl populations move to new areas to meet their biological needs. In general, waterfowl typically spend late spring and summer breeding, nesting, and raising young in northern latitudes and during fall and winter move to southern latitudes with warmer climates. This causes national boundaries to be crossed during migration. The extensive migration patterns of North American waterfowl (ducks and geese) call for special conservation strategies, such as international treaties, flyways, and hunting stamps, to be implemented.
