Expounding on a response I made in on a different post:

Whatever you bring to Burning Man, you need to take with you when you leave. This doesn't just mean MOOP. This means your broken bike, your soggy couch, the 10 garbage bags of trash that you didn't consider you'd have at the end of the week.

Don't be that asshole who dumps your excess stuff in someone else's area when no one is around to catch you. In terms of what Burning Man standing for, that makes you pretty fucking low, as you've just failed at Radical Self Reliance, Radical Civic Responsibility and LNT. If you leave something for someone else to take, without actually asking a human to take it, you're not gifting, you're being a shitty Burner.

If you're truly out of space in your truck, ask your neighbors if they have room to take some of your trash and offer them some cash if they'd have to pay to dispose of it (some of our west coast members take as much of our trash as they can, but we also have to pay to give it to the Reno dump). Or do the miserable, shitty thing and repack your stuff even tighter so the trash fits. Resign yourself to the idea that your poor planning may mean you get a little garbage juice on your stuff. Yes, that sucks, but it's a lot shittier to make it someone else's problem.

Every year now, BMorg posts photos about the massive garbage mounds left behind for them to deal with. Personally, I hope they eventually have some drones flying or something that tracks who leaves this shit so those people can pay hefty fines for dealing with it and/or be banned from the event.

If anybody else feels like venting a story about dealing with someone else's trash, I'd invite you to do it here.

And everybody, remember to bring extra garbage bags - heavy mil ones can be a life-saver. Check out how full your packing going in, and remember that you're packing most of that out (minus food and water), but that you (and possibly your camp, if you have one) will be generating trash that you need to haul out too. Take responsibility and be prepared yourself instead of pushing it off on someone else to deal with.
