Yay, daylight!

The hospital has lots of nice old trees lining the road to the original building (immaginativly named after the year it was built...)
Some are smooth, some very gnarley or twisted. Most have their very own little ID badge.
I suppose it is so they can prove they belong here if they are challenged by security in the event of another tree imposter situation like the famous fake tree scandle of 2003.
Or is it so they can be sent home if they get lost...
