MARIJUANA!

Jack Elrod's Mark Trail discovers marijuana in the forest! ...using an aerial photograph.... which seems like an egregious stretch.  I mean, sure, there are certainly people who grow hidden fields of pot in forests and sometimes on federal or state lands. And there are certainly ways to observe such crops via aerial reconnaissance.  However the dialog is so ridiculous here and the old-school technique with a magnifying glass.  Well, it's Mark Trail.  What's one to expect?  Actually if I were him I'd be a lot more worried about the gigantic bird that's about to attack the buildings he's in.
