Dear bluebicycle,

Thanks for posting this. What a great topic!

I do many of the things you mention. I am also designing a city using pen and paper. This started as a project at the beginning of flu season and now is continuing during the SARS-COVID-19 pandemic. I wanted a huge, complex, challenging and fun project that would fill my time and thoroughly engage my mind. As of today, I have produced about 762 pages.

Sincerely yours, -- Yao Wen
