Over the last year or so, I've started to get heavily back into using Emacs and the Org mode package (for taking notes, organizing yourself, and more). I've also started dipping my toes back into the water of giving short presentations. I've been wondering how to combine Emacs with giving talks.

I travel a lot on business. I'm not much of a car guy, so when I have some free time, I prefer to walk or bike around a city. Many of the cities I've visited on business have bikeshare systems, which let you rent a bike for a few hours.
