I think that the SF Bay Area’s Caltrain announcements are (or were) based on simple phone calls, because I was shocked to hear some telemarketer’s robocall come over the system once, a few years ago.

Since I’m a fair and reasonable sort of fungus; I agree that it might be a good idea to let the Librarian of Congress examine the creation of limited exemptions for recreational purposes(with due input from stakeholders to keep input from the public in its due context, obviously); exclusively in areas deemed to be of no security, intellectual property, public order, or trademark concern. Baking soda volcanoes, say, of not more than one (1) liter reactant volume, with an appropriate permit, seem like a wholesome and nonthreatening activity for everyone.

To keep our sidewalks clean, release of bodily fluids by homeless citizens and google bus toilets will be restricted to parking lanes. Thank you citizens and visitors to Frisco.
Wait, is this one of those Cambridge Analytica tests to work out how old I am?
Damn…
Don’t you need a license to broadcast on a lot of frequencies already? From TFA:
[Bastille] couldn’t easily try Seeber’s technique via radio in a test setting without risking a violation of FCC regulations
You’re thinking like an engineer, not a politician.
