About the Container
You are looking for a brown, half-gallon-size drink cooler. There is plenty of room for trade items and travel bugs. Please bring your own pen.
About the Location
This is a fairly wild patch of the Milwaukee River Greenway. This area can be muddy if there has been a lot of rain or melting snow. The easiest approach is to curve around uphill away from the river. When you are directly uphill from the geocache, head into the thicker brush.
Some stealth may be needed if there are people nearby. As always, should you be caught, the Secretary will disavow any knowledge of your actions.
About the Spy Gear
Tranquilizer guns are a well-known device in spy movies and TV shows. They seem to come up most often in spy comedies because they help to lower the stakes and keep the tone light. One example is the television show Chuck. The main character, Chuck Bartowski, prefers to use non-lethal weapons like a tranquilizer gun because he doesn't want to hurt anyone.
Tranquilizer guns exist in real life, but they're made for animals and not for people. Human bodies and circumstances are too variable for the guns to be safe. It's too likely that the gun would administer too little of the drug to be effective or too much, which could kill the person. They are also too slow. The drugs take time to enter the bloodstream and take effect.
The modern tranquillizer gun was invented in the 1950s by Colin Murdoch, who was studying wild goat and deer populations in New Zealand at the time. The dart is a syringe with a hypodermic needle. It's propelled from the gun by means of compressed gas. The paralyzing drug is kept inside the syringe by placing a cap over the hole in the needle. Upon striking the target, the cap is punctured and the needle tip continues into the target. At the same time, the fluid is no longer restrained by the cap, so a compressed gas chamber forces the injection fluid chamber to empty into the target.
