We're already there, sug! Try to find a Coke or candy machine in a school these days!
Personally, I don't think those should have ever been put in the schools to begin with.
And now that most districts have done away with required P.E. (which is completely retarded, but that is a different discussion), the schools need to do something to get the lard of the kids.
To me, it is a different thing if a school district decides to get rid of vending machines (which I support), vs. some gubmint wack job deciding for everyone that they are not allowed to have vending machines (which I do not support). I do not know which is more prevalent.
