All of lifes questions

I don't really understand these "hippies use backdoor <--->" signs, is it some kind of joke that you only get if you are a hippie or were alive in the 60's or are stoned on "grass"? And why has this version of the sign been modified to only point one direction?

Here is a broken house raised up on cinder blocks. Is this what you put in your front yard when you are a rich hillbilly?

I really wish I needed a sign made.

This is the mother load of milk crates, you know how many makeshift bookshelves you could make out of all those?...a lot. Guess where I found them?...the milk factory.

Awesome indeed.
