Grammatical correctness in using "of" following inside/outside
Is it grammatically correct to use the word "of" as in "outside of...", "inside of.." when making a reference to an object? I've been taught that this is improper usage due to the redundancy, but the english spoken in America has its own flavour and breaks the rules of grammar.

The 'of' might be omitted in formal writing, but otherwise, there is nothing wrong with its use.
