GeoStar Cache Recovery Vehicle

To travel the land in search of caches and cachers while we explore new places and meet new friends through the joy of geocaching. Maybe we will meet new friends, maybe we will see new places, maybe we will get honked and waved at, maybe you will flag us down and we can chat and maybe, just maybe, I can peel myself off this window...

 Minding my own business one day just flittering around I see this blue Hyundai bounding down the trail. Paying it little attention I went about my buggy business and watched him pass. Clearly the driver was not paying attention to the road as he had his head down staring at some silly phone or something in his hand. As I attempted to fly across the road this knucklehead ends up in reverse at about Mach 4 and before I know it, SPLAT! here I am stuck on this guys rear window... 
 Now, do you think the driver even cares? NO! Of course not. Instead of helping me off the window, he gets out of the car and proceeds to march into the woods with his shiny iphone in his hand. I don't know what he was looking for, but all he found was some tupperware container with happy meal toys in it. He scribbled something on some paper, probably a nasty note or something, threw it back in the tupperware, set it under a log and jumped back in his car. Of all the nerve! First he clobbers me then he just leaves a nasty-gram in some tupperware in the woods and drives off like nothing happened.
 Anywho, now here I am, stuck on this guys window traveling about the land as he meanders to and fro, stop and go, chasing tupperware, ammo boxes and little tiny containers and writing notes in them. Sometimes he even puts some additional little trinket inside these containers prior to leaving them in the woods... What is this guy? Some kind of sadistic, bug smashing, tupperware tracking, fancy phone having, no attention paying terrorist leaving notes to all his terrorist tupperware chasers around the country?
 Help me find out, and help me off this darned window before he manages to drive off a cliff!
