Roof top marijuana grow exposed by helicopter covering bike race

Evidently the excitement in this bike race video from Barcelona is the identification of marijuana plants growing on a roof. Volunteer marijuana is unusual to find on a Spanish rooftop, hence the surprise. Local authorities cleared the weeds.

Deadspin:

Catalan cops seized over 40 cannabis plants from a rooftop near Barcelona yesterday thanks to information from an unexpected source: a TV helicopter broadcasting this month's Vuelta a España. Stage 8 of the race finished in the town of Igualada on Saturday, and as the race made its way through the city streets at the end of the stage, helicopter footage showed a whole bunch of (presumably) dank weed on someone's rooftop.
