I was moving my Woodmizer yesterday and some wasps took offense when I stuck the jack rod into one of the holes where they had a nest. Nest thing I knew I got hit right above my ear. I hit back with some brake cleaner that was nearby and finished moving the mill.
Last night I woke up after sleeping on that side and that side of my head is sore, red, swollen and I have a headache. DanG bees!
