This is a pretty sweet idea for the community. Too bad there are no cute, red phone booths on this side of the Atlantic.
But there are decrepit shacks and empty buildings in parks. I'm sure parts of those can be converted, if the city really wanted to do it.
That's one of the things I've learned recently: people will do things if they really wanted to. Although sometimes, people will do things if they don't want to too, but that is a choice as well. If a student chooses not to finish the writing assignment, then it means they accept a zero for their grade.
Anyway, I think it's a great idea. Something small, and maintains itself. Those opposed will use the excuse of "vandalism" and "increased gang activity." Which may or may not be true. At least the city will have well-read gang members, no?
