Hunker in the Bunker Traditional Cache

My first ever hide!  Thanks to GO Geiger for letting me know which of his puzzles I needed to solve so I could find a spot out here.  I don't know what this building used to be, but in its current state it looks like a bunker.  You're looking for a 30-cal ammo can, it shouldn't be a very difficult search.  "Poison plants" attribute is simply because this is in the woods, and who knows what might grow around it in the future-- but when I placed it in mid-summer, there wasn't anything nasty around.  Original swag includes some toy cars and trucks, play dough, spare batteries, and gel pens.  There should be a pen in the baggie with the log-- I'm one of those who roll their eyes when I see "Didn't have a pen" in a log, but I'm also forever arriving at the first cache for the day and realizing I don't have one!  There's a nice FTF prize in the baggie with the log, I hope you aren't co-finding...
