My trip to the arboretum

No longer welcome
In Boston arboretum
Missed "no climbing" sign

From thirty feet up
Lecture by cop on tree care
Didn't quite sink in

"Preserve town's future
By not touching the foliage"
Blue lights flash below

"Show me your ID!"
I wonder: does he mean me
Or "Western Hemlock"?

If they're so worried
About trees getting broken
Why make them of wood?
