The Town of Florence, AZ puts on historical lecture series each month. They are always well put together and on interesting topics that relate to the area specifically or Arizona in general. Absolutely love them. If you are local or will be visiting around the month of January you should check them out. All the lectures are free to attend. They do fill up fast though so you’ll want to get there a little early.
There is usually a survey about what you thought at the end, so make sure you have something to write with 😉
