I received mail from Tracy Burrows at SDOT today. She promissed on SDOT's behalf to address the problem of SDOT crews leaving spikes in Seattle streets. The solution is to leave spikes in Seattle streets.
Well, OK, she did say they'd pound them all the way into the pavement. It sounds scary, but if SDOT actually does it, and the spikes stay there, I'm happy.
Of course, SDOT crews still have to find the spikes. Tracy told me that SDOT went looking for a spike I told them about, and couldn't find it, even when I told them almost exactly where it was. I saw it on the way to work this morning. The spikes can be very hard to see in asphalt, despite their size, because they blend in very well. That's a big part of the problem, in fact.
