Done and dusted

That's the last exam of the semester done with, except of course for the grading, but that can be done from home. Most students have left already or are getting ready to leave. In celebration, I put the sheep out to graze on green grass for only the second time this spring.

Here's your semester-end picture, from Alecia in Marketing. Arthur and I were testing the students' small home-made turbine generators outside in a variable breeze, when we discovered that the cooling fan on Mr. Fox's greenhouse made a natural wind tunnel.

Much more effective!
