I always thought that entering the black market would require selling drugs or guns. It turns out that I can just sell plastic straws:
A California coastal city has become the latest municipality to ban plastic straws, enacting what is potentially the strictest plastic prohibition in the country.
Santa Barbara earlier this month passed the ordinance authorizing hefty fines and even a possible jail sentence for violators who dole out plastic straws at restaurants, bars and other food establishments.
That lowers my initial capital costs significantly!
