Possum magic: mapping an Australian children's book

Our brand-new baby received a fantastic picture book as a gift: Possum magic, a classic for Aussie kids. Thanks, Miles! In that book, Hush the possum and her Grandma Poss encounter different Australian animals and travel across well eat their way through the country. It is an adorable story with great illustrations! Reading it will make you feel like travelling to Australia, for instance to useR! 2018, except you shouldn’t because it is a very scary country:

However, you can travel and learn geography without leaving the comfort of a snake-free home… by mapping Hush’s adventures! Which is what I decided to do.

Where to live in the US

I was fascinated by this xkcd comic about where to live based on your temperature preferences. I also thought it’d be fun to try to make a similar one from my R session! Since I’m no meteorologist and was a bit unsure of how to define winter and summer, and of their relevance in countries like, say, India which has monsoon, I decided to focus on a single country located in one hemisphere only and big enough to offer some variety… the USA! So, dear American readers, where should you live based on your temperature preferences?
