The term 'pipe dream' came from the East (Near, Middle, and Far) many, many years ago when smoking opium was legal. An opium parlor would have large water pipes and customers would sit around, smoking the opium and get into dream-like (doped-up) trances. The saying came to mean anyone who has an impractical idea, which is what it means to day.
Of course the pipes running through this area don't have anything to do with pipe dreams other than wishing I could partake of the profits. Which is of course a "pipe dream.'
