1. No tear of the retina was found today (detachment of the vitreous is what's causing the floaters and flashing lights).
2. Trip to Michigan delayed for a month until I'm rechecked, but that just gives me more time to settle things here at home first (and to plan my route to and from Michigan).
3. Got the new lens for my new full-frame camera, and wow, what a difference it makes for my photographs!
