Those northbound CH-47 Chinooks looked to be barely over treetop level, but the rotors are 60 feet in diameter and they were much higher than they seemed. Shook the house and brought all hands outside to watch the show.
I remember getting a tour inside one, a long time ago, at a military air show.
Something weird is going on with the Northern Cardinals at our feeder. First a female missing a leg, now a male minus his head feathers:
Bald Cardinal – right side
A view from the other side:
Bald Cardinal – left side
A bit of searching with the obvious keywords produced that writeup, which suggests feather mites or other parasites. Given that this was in March, that cardinal is definitely not molting!
Those pictures are tight crops from a hand-held Canon SX230HS at dusk, through two layers of 1950-vintage glass. Sorry about that, but the bird spooks whenever I crack the door open for a better view.
While I was puttering around outside (an admittedly rare occurrence), a deep thuttering over the northern horizon eventually resolved into a formation of four helicopters. Hard to tell at this range, but they looked like Black Hawks southbound for the Stewart Air National Guard field.
Our Larval Engineer reports that the college ROTC contingent includes some pilots-in-training who regularly land Black Hawks on the campus outfields.
The local construction equipment supplier deploys otherwise-idle yellow iron in all the parking lots in preparation for snow season. They haven’t gotten much use this year, which is OK by me.
A Komatsu excavator behind a bank sports some puzzling warning placards:

Maybe read the manual before / while being backed over?
The on-line driver safety review course that gets us a 10% premium reduction has a few glitches:
Driving Quiz
They evidently randomize the answer choices without considering spatial constraints. One question had “All of the above” as the first choice, with all of the other choices being valid.
The helpful tech support voice said they’re looking into fixing that…
OK, time for a Pop Quiz: Is it possible for a human being to write perfect straight lines diagonally across a ruled pad?
Answer: Evidently so. Consider this screen grab…

Taking the course online has the advantage of not requiring a trip or two to a classroom, but kills an hour a day for a week. It’s still a win, although it’d be much better if they didn’t use Adobe Flash.
