I recently took a very long trip across the country.
I went from very far north to the south.
It took a few days on the bus. The bus would stop often, at different stations and cities and sometimes even for a few hours, and we could go and get some food or even see a bit of the city or town that the bus stopped at. Sometimes the bus would be changed too, or the driver would change. The main problem was that the air-conditioning or the heating in the buses would really vary. Up north where I started it was pretty cold when I left, so the bus needed good heating. But the air ducts just did not supply the warm air the bus needed. I felt like I might even catch a cold. Then the buses were changed at one of the stops, and this time the new bus had really strong heating. It felt like a furnace in the bus. It was really uncomfortable. As we went further south it got warmer and warmer, until it was pretty hot. Sure enough the different buses had different levels of cooling equipment and air conditioner quality. I was lucky I had a heavy coat! It was kind of surprising the air quality and the temperature levels in the different buses were so different that is for sure. At the end of the day the price of the ticket was OK though. It was not that cheap though. But it was a pretty efficient and safe trip, and that is the main thing.
