Been reading of the misery and disappointment of some and the sheer ecstacy of yet others at large rallies and get-togethers of the cult, I have a few questions as I have yet to go to such an event.
I have read of "pump out service"
I got to think this is sewage removal. Right? So how does this work? Do they dump into a blue boy and suck that into a truck? Or do they connect directly to your outlet and suck into a truck? Is there any back flushing included? Is this generally very neet or does a bit of "dripping" usually result? How many rows over can you usually smell the pumper coming? Is it the Airstreamy thing to do to invite the operator in for coffee and cookies?
Also and this is a rather un-delicate

subject, but I have wondered.
Is there a generally fecal air to the enviroment at a rally site?
Seems after a few days in the 90+ degree heat there might just be a whiff of... let us say "de scat" in the formally festive fields.
