Thanks for the information on rubber sidewalks, particularly the boingy incident from Iowa in 1875. I found it as funny as a rubber crutch and laughed out loud.

Hi David,

I always look forward to these snippets and your books. But the message below necessitates informing you that using recycled rubber tires for any use is a really really bad idea. In the last couple years it was discovered that a relatively benign chemical (6-ppd) in tires that is intended to lengthen the life tires becomes incredibly toxic to coho salmon when altered by UV light and becomes 6-ppd-q. There are many articles published about this. I encourage you to read a few and then encourage your subscribers to educate themselves on how unfortunately bad this stuff is.
