I am not in any way connected to it or anyone involved in it, just spreading the word. There is a spreadsheet they ask you to use, which I think is a bit silly, not everyone has excel, but whatever. If you'd like to participate but don't know where any are, here's a link to map where the colonies have been getting marked

happy counting!
