Please stop being stupid, both of you.  Vandalism, if you bothered to read Wikipedia:Vandalism and not just link to it, is a change of content made in a deliberate attempt to compromise the integrity of Wikipedia.  What I did—and you know it—was to remove travel guide material from the Statue Park article in an (apparently vain) attempt to improve its quality.  Further, I was careful to write an edit summary explaining exactly why I did what I did.  Therefore (1) it was constructive, (2) I do not need to use the sandbox and (3) I do not need to learn more about contributing constructively to this encyclopedia, although you might.  Of course, you are perfectly free to revert any edit you do not agree with, but please leave off the bullshit notices on people's talk pages.
