This cache can be found, as the title suggests, in a place where dirt, rock, wood, and metal meet. Also, depending on the time of the year, maybe some leaves or snow. Look for where all of these elements press out toward the sidewalk, and you'll be pretty close.
This is in a camoflauged pill bottle. It should be accessed only from the sidewalk, and there is no need to go on the resendential property (though we do have permission from the residents to place this here). Please try to put it back in the same place you found it so it doesn't arouse too much suspicion.
There is a "valuable" FTF prize in there that you are free to take, and space for a few other trinkets to trade.
