Good morning. It’s the end of the week, it’s a bit overcast and the traffic lights are out around the Mall — so if you are driving, treat dark intersections as four-way stops.

Or, don’t drive at all. Gasoline prices hit an all-time high here this week, at an average of $4.21 per gallon. That’s an average. Just to fuel our outrage, let’s also look at the big-oil execs’ justifications yesterday before a Senate committee on why they deserve tax incentives.

Those 800 emails released by the D.C. Council committee investigating Mayor Vincent Gray’s hiring practices seem as rich as Wikileaks’ exposure of diplomatic cables. The city’s employees talked about job applicants’ weight and language abilities; previous disclosures showed bureaucrats gossiping about Gray’s girlfriend. Mike DeBonis, btw, will be live-tweeting today’s Friday hearing featuring Lorraine Green, starting about 11 a.m.

If you’re in a motorized wheelchair, or you have friends or family members who are, you know the frustration of trying to get a local taxicab that can accommodate you. Finally (how many years after the Americans with Disabilties Act went into effect?) 20 local cabs are properly equipped and will be available 24/7.

Are we all nuts? The D.C. Squirrel talks about the end of the world, which as any resident of the DMV knows, is May 21 (or so say all the end-of-times signs that have been popping up all over tarnation).

It’s Friday! So here’s some weekend fun: Tonight, the Blind Boys of Alabama are at the Birchmere; Saturday, the second half of the embassy tour ; Sunday, there will be yoga on the Mall. If you prefer eating to stretching, here’s a list of food-themed festivals for the month, leading off with St. Sophia’s Greek festival.

There’s more, so much more, but we are out of time. Keep an eye on PostLocal and all our local bloggers today and through the weekend. I’ll see you Monday.
