I expected to read about a lost cat

Right outside the door to our office building, I saw a flyer advertising a PA system for sale. It seems that someone has a lot of this equipment that they need to move in a hurry. The seller has probably put their ad in the classifieds, maybe advertised on some local music websites, something like that. That's my assumption. And hey, their flyer has a website address.

But don't you think that it's a bit extreme for them to be stapling their advertisements to trees?
