Best way to learn racket?

Been spinning my wheels the last couple days, trying to find a foothold to start from. Partly because I don't have a firm understanding of where racket fits in with the larger lisp world (and seeing arguments all over about whether that is or is not a relevant distinction).

I think I'd like a walkthrough/tutorial of the basic language itself to start with, something like the python.org tutorial.

Ultimately I'd like to be using racket (lisp? scheme?) similar to how I use python, for simple scripting with room to go large when needed.

Where would you, the experienced racketeer (schemer? lisper?) tell a newb to start?
