Industrialized Cyclist Notepad


Just let him by

(Had an interesting passing incident today, as a matter of fact, on some singletrack south of town. I was about to pass a runner. He heard me coming and kindly stepped off the trail — almost directly onto a huge rattlesnake. Very large snake, as thick as a mason jar. Awesome. It waved its huge head around at us like a cartoon cobra for a few seconds, then we all went on with our business.)

New Zealand has some nice trails, so I’ve been told.

First time I’ve ever heard of something like this between trail riders. Didn’t watch the video:

Brizzell said the incident happened after he asked Dalton to let him past, in line with trail etiquette to let faster riders through.

However, Dalton did not give Brizzell space and eventually their argument boiled over into a physical confrontation.

Brizzell said he was strangled by his helmet strap and eventually bit the man’s finger.

Plutonium-239 and Americium-241 Contamination in the Denver Area

Now with Cesium sprinkles!

A 1972 article notes a ‘thin layer’ of Pu-239 contamination. I suppose that’s good news of a sort. The operators of Rocky Flats, however, went on to illegally incinerate and dump waste at least through 1989, when the plant was raided by the FBI.

Measurements of 239Pu and 90Sr in the top 1 cm surface layer of soils show that in this layer the 239Pu contamination in offsite areas just east of the Rocky Flats plant ranges up to hundreds of times that from nuclear tests. In the more densely populated areas of Denver the Pu contamination level in surface soils is several times fallout.
