Firefly T-Shirts for Browncoats
Back in 2002, master of cult television Joss Whedon brought Firefly, a brilliant fusion of science fiction and western, to the airwaves. With a unique setting and a gorram shiny vernacular all its own, the series made a big splash, then was promptly cancelled, only later getting a film followup in Serenity. Even now, the fans, Browncoats, are continuing the fight to revive the show in whatever form possible.
Take our love
Take our land
Take us where we cannot stand
We don't care, we're still free
You can't take the sky from these tees.
