Train to Bucharest

This was a bit of an adventure - I was worried I was going to lose my passport for a bit.  I took the train from Sofia to Ruse (on the border), and then had to switch trains.  They checked passports before getting on the train by collecting them from people on the platform, taking them to the office, and then coming back to the platform and just calling out names.  Luckily, I got my correct passport back right before I boarded the train.  Once we crossed the border again, we had passport control with a Romanian official who looked at each passport individually.  The officer who checked mine said I would need to quarantine for 10 days unless I was vaccinated...  Yay!  I am vaccinated, so no need to quarantine!  I arrived in Bucharest with no hassle.  My hostel was a five minute walk from the train station, so that was nice and convenient!
