I took the summer off. No PD at all. Didn't even think about school. I grew sweet corn and worked on fixing the culvert under the bridge on my farm. I hung up my tap dancing shoes. This year I will teach kids and avoid PD as much as possible. After last year, I am PD'ed out. I have 35 years of PD under my hood, and it is mostly sounding like warmed over stuff from earlier decades, with new titles, new speakers, and new names for old concepts.
