@akkartik I really appreciate that. I casually followed some Racket tutorials in the past, but this is the first time I've taken a serious look.
I'm starting with both The Scheme Programming Language and Structure and Interpretation of Computer Programs.
@daremo Feel free to ping me if you have questions or need a sounding board! I'm not a huge expert, but I spent a long time on the axiomatic roots of Lisp in the past: http://akkartik.name/post/wart
