You are looking for a small pelican case with room for tradables. Stealth is required as it can be quite busy here, especially during the daytime on warm, sunny days. It should be a fairly easy find. The resident squirrel is always on the lookout for out-of-control golf balls, so he may be watching you from nearby. Please make sure the case is securely closed when you put it back in place to keep everything from falling out. Have fun!
