We take the street car to the Octagon stop then walk across the street and downstairs to the M1 subway, known locally as the underground. This is the first subway line built in Hungary, and has been in constant operation since 1896. The train cars seem to be the originals but they have been maintained and updated through the years.
Our next stop is just north of Hero's Square at the Agriculture Museum. There at least a hundred in line awaiting admittance, 70% below the age of 10. Nope. Not for us today. We have a nice coffee in the patio restaurant on the pond and plot our next steps.
We return to the apartment and I setup for some hours at my consulting gig. Ah - the flexibility brought by the internet and remote work. :-)
