A coworker told me that she moved to Oregon in 4th grade and went to a magnet school in environmental conservation which mostly consisted of weekly field trips to remove invasive blackberry bushes and English ivy. This is the most PNW thing I’ve ever heard.
@irene I went to a college-prep school in Monterey that still has the students perform minor maintenance tasks on campus. (It's a very small school.)
One of the tasks is collecting invasive iceplants.
