Hi!
I usually lurk here and read a little. I don't think I've skipped a Skeptiko episode since its inception in Feb '07 though!
An argument against dog telepathy made me do a mental doubletake - it went along the lines of "well, dogs can hear the individual hum of a car from 20 miles off, you know" but I couldn't find anything on google about it (yet).
I know that Polar bears are supposed to be able to SMELL a seal from 20 mlles away in the binding whiteness of the arctic.
Hearing an approaching car's special whine against the noisy backdrop of a Californian city, hmmm... other story?
250 yards is all I could come up with yet (I'm not very good at imperial but I do know it's a considerably shorter distance). The 20-Mile-debunk argument came up in the youtube comments. Can anyone substantiate this?
If true, it would require that some changes be made to the experiment.
Marco
