Trees!

Not sure if anyone's reading this anymore, but it looks like the trees are back. I had a reference question this evening about a certain kind of ash tree. As I was helping the student, I recalled being warned about the tree assignment in previous semesters. Not sure if this is the same assignment or if there will be more students, but I actually got to take someone to the tree reference books. Come to think of it, the public library also had some sort of infamous tree assignment where the high schoolers came in and checked out every darn tree book in the place. What is it about trees??
