I saw dead crows in the woods both days this past weekend. While riding in Boxford on Sunday, I saw these signs plastered all over the place:
When I first moved to New England, I learned about Lyme Disease and ticks. Then West Nile Virus and mosquitoes came to the limelight. And now Eastern Equine Encephalitis. This last one, although fairly rare in humans, will kill you. Both of these viruses kill birds, and I wonder if that is what's killing the crows.
I don't tolerate bug repellents very well, especially DEET. With ticks, you have a little time to clean up and remove them before they can transfer Lyme disease. Mosquitoes finish their job in less than a minute. I remember slapping a mosquito when my derailleur cable broke towards the end of my ride Sunday. Scary stuff.
