This derelict property is going to take some work.....
 
Clipping the lock the first Impressions is pretty much a rapid progression  of the Ross-Kessler stages. 
 
Apparently the curbside trash pickup of modern society is for suckers when you can easily just pick a room and fill it up with your garbage.  Room Full?  Well, that is what doors are for apparently.
 
If you ever wanted to know how much trash you can fit in a house then I'm going with the highly scientifically devised .10 cubic yards per square foot.  No really, I did math on dumpster loads on that and everything.
 
Successfully cleaned without releasing any super bugs or zombie apocalypse so onwards to Stage two....
