Signs, where..?

Today it was beautiful outside, so it was time for a stroll. My goal was to walk to Leiden, but somehow I got lost in Hoofddorp. And because I refuse to backtrack, I headed to Haarlem instead.

[ and from Haarlem I walked back home... ]

It was dark when I finally arrived, and now I'm eating pancakes...

There were signs near Schiphol, but they weren't there in Hoofddorp...
