  1. Thanks for the tip about World Snake Day. It inspired me to do an item (crediting you, of course) on my wild gardening blog.
    I’ve only just discovered your blog but am getting a big kick out of it. Will have to check out your posts on Skepchick.

  2. Thanks! I’m still looking for the source of the holiday–I see it on calendars all over, but not much other info.
