I know it’s an unpopular opinion given current circumstances, but I’ve always been a huge nerd about Russia. The history, the geography, the music, etc. And as an American, I’ve always found it fascinating how U.S.-Russian relations have fluctuated over time. We’ve gone from allies, to enemies, to frenemies. This doesn’t mean I support Z or Putin, of course. What are you a nerd about?
I second the recommendation for Not Just Bikes on YouTube, probably one of the online content creators who’ve had the biggest effect on me. Another good one is Oh The Urbanity!
I haven’t gotten around to reading it yet, but I’ve heard many recommend Confessions of a Recovering Traffic Engineer written by the founder of Strong Towns. Honestly, a lot of sources I’ve seen reference this book or are inspired by Strong Towns.
