I just set up my laptop to interface with our network printer. I had never gotten around to doing that before now. My laptop's system just said "hey, cool, I've got an open source driver for that"--and it did and now I can print. I printed two concert tickets for tomorrow night.
I am debating whether to stay near or go far tomorrow morning, but either way, I plan to be binoculars and camera in hand--and to preface everything with a dawn walk with my wonder dog.
