A big fat zero this week, in part due to an enormous number of repeats. Both Comedy Central shows are off in preparation for their week in Washington, and the only network late night show not in repeats is Jimmy Kimmel Live. The repeats have no listed guests that fit the category.
At least the USA Science and Engineering Festival is still going on, with the schedule of events ramping up in advance of this weekend’s Expo. I’ll have more information on the Expo later this week, because the schedule is sufficiently full that you need to really plan your visit.
