We don't have touring riders? That's funny. We have a whole bunch of everything here. Everyone is welcome. Safe riding and gear is encouraged, but in the end only you are responsible for you.
I did damn near the same thing several years ago. One of the first oil changes I ever did on a bike. Overfilled the oil. Thought I could drain some out. Plug slipped out of my hand and slid down the hole in the middle of my oil drain pan.
