Enjoying the transition to fall right now living in such a city.
Im regents park london, they let some cut trees rot on purpose, years later there are still no funghi visible growing on them, while in a forest that happens. Ive also not met a single mosquito there in years.
Most city parks are mere deserts to me. It sure still is healing to be outiside, but calling that "nature" is a blunt lie in my ears.
One is like 8min from my door, could even take a bus since there are stops on the edges.
I've been trapped in the concrete-jungle part of SF for a while, and — while I do really want to escape to a better, greener city — it's oddly difficult to find an alternative. I wonder if NYC may be the only viable candidate.
I believe it is one of the greenest cities in the US, I used to know a few people from there that I'd connect with over the years at business conferences, and they absolutely loved it there.
They are not skyscraper-level breathtaking like many US cities and not as dense - but have lots of advantages (walkable, good public transport, rich cuisine, higher food quality in general, less homelessness or other social issues, … not even talking about working here with much more vacation/free healthcare/…).
Ultimately you mentioned museums - well Europe has stuff that is thousands of years old. Lots of stuff to see and discover. I personally like to go to authentic medieval festivals or viking meetups for example.
