Starting ..... now.
Actually, it starts next Monday, and "it" is my sabbatical. I plan for it to be more of a stay-battical, spending time on electronics, flameworking, hiking, and running. Mostly enjoying the embarrassingly good weather the Bay Area offers during the summer. Melinda and I also have some travel planned for mid-August, to Pasadena and the northeast and in mid-July to Seattle.
I've been told that the time will fly by and I fully expect it to do so. That's why I expect my first activity on my sabbatical will be to sleep in.
