Santiago is about 100 km from where I live, and we took the bus to get there.
There are 6,603 miles between Saint Louis and Ferrol.
I took the bus and walked! The public transportation in Spain is awesome, and most people use it regularly.
The most interesting place I visited was Santiago de Compostela.
I have this coming week off for "Semana Santa" or "Easter week", and I plan on renting a car to drive around and visit some of the natural parks around Ferrol.
