I'll never be your beast of burden...
Here is another installment of my caches themed after Rolling Stones songs. Beast of Burden was first released on the 1978 album Some Girls.
Not that our beasts' are ever a burden on us, it is a burden on our emotions when we have to bring them here. You will be looking for a black bison tube, so BYOP.
Congrats to RICK+REESII Dog for the FTF!
