I still have pine resin on my backpack after I threw it down under a red pine, those aren't called Pinus resinosa for nothing. Still remember the campsite, scenic and sandy, very nice view..
As far as the dog barfing in the tent, maybe the dog doesn't like camping. Or maybe he drinks too much on camping trips, like mentioned on the litterbug thread. There are vids out there showing what happens although it isn't dogs that are doing the barfing. Not gonna show those... pigs, unspeakable, hideous.
