The sky was overcast but the wind was calm. A temporary flight restriction popped-up and limited any action to the southwest, so I did a few turns in the KPNE pattern. Their radar was down but the tower operators did just fine. Still, I opted to head to N87 and hang-out there for a little bit. Must've been more tired than I felt because my landings deteriorated as the day got on. That last one almost earned me the nickname Maverick. Or Deductible :).
