Way marks

I'm spending a month following markings across a country, hoping it leads me to Santiago de Compostela. It's really a crazy concept. Way marks obviously show the way to Santiago. They come in all shapes and sizes, they can be ANYWHERE, and they can be difficult to follow. Getting in and out of big cities proves especially challenging for me, so I always choose to walk with other pilgrims for these parts.
