Got up there, spotted some tourists, gave them a quick tour of the observatory. They were from the Los Angeles area. Got my work done. Gave some more tourists a quick tour. They were from New York, but had grown up in India. This was funny since I was in New York early last month, and in India last fall. Drove back down. Recorded my trip as Hilo-Mars-Hilo in the vehicle's mileage log, since it's April Fool's Day.
Watched part of the Merrie Monarch Festival, except when my daughter demanded that we channel-surf over to "Trauma: Life in the ER" on Discovery Health.
Eventually, got some sleep.
