I guess I'm old fashioned too, but it's pretty funny when you're out on a ride and your mate has to stop because their derailleur ran out of batteries.
I've ever had a shifter cable fail on me in 20 years of riding, including stints as a bike courier and two continental circumnavigations.
The hardest part will be hiding the light/smell/sound.
As an aside, one of my housemates was dealing out of our house (unbeknownst to me) and we wound up getting raided.
It was awful, Id seriously reconsider growing secret plants at home unless you're okay with the possibilty of pigs fucking up your parents/siblings rooms.
Also from the article, this seems a lot more plausible:
The flatlands of Carmen were once a playground for giant children. One day, they initiated a contest on who could bake the most mud cakes, gathering mud and "baking" them under coconut half-shells laid flat on the ground. Before the contest could end, however, the children were called home. After a while, they returned to the area to witness their finished creations and left them undisturbed out of admiration—the baked cakes thus became the hills.
Did you mean to type 'relevant' or are you suggesting it's a zombie project?
