If you drive the border of Texas it is a trip more than 40 hours long. Two straight days of non-stop driving. The US is stupid big and has an insane amount of roadways, you could drive your whole life and have roads you have never been on.
This has me curious about the extremes of the relationship between perimeter length and area of various states. Time to go down a YouTube rabbithole I think, stand up maths probably has something on it.
