I've prepared a handout to go along with my upcoming talk for Prescott Audubon. Unfortunately, I don't know how many to expect at the meeting, so it's probably best to post the handout here where everyone can have a copy if they like.
This should make the handout available to a wider audience, and also provide a color version suitable for printing at home. Please feel free to print out a copy. No need to bring it with you, unless you want to use it to take notes.
See you there, Thursday.
