Interlude: What Vehicles Say About Temperatures Within a Volcanic Blast

Interlude: What Vehicles Say About Temperatures Within a Volcanic Blast

In our previous installment regarding the effects of the May 18th, 1980 Mount St. Helens directed blast on vehicles, we learned a valuable lesson. I will call upon commenter Angusum from Boing Boing to sum up: "The main thing we learn from studying vehicles trapped in the path of a volcanic eruption is that you should try very hard not to get trapped in the path of a volcanic eruption."

Twelve - Okay, Eight - Months of Rosetta Stones, Plus Reader Extras

One tradition in the Hunter household is that things always fall apart over the winter holiday season. This year, the cable quit in a snit, and the computer decided tonight that speaking to the internet was not part of its job description.
