2014
Andrew Seidel (Andrés) did a couple slideshows about his trips to Antarctica and China. Unfortunately, I did not record any of these. Andrés took excellent photos!

Trans Am Bike Race
On June 6, I gave a one-hour presentation on the transcontinental bike race I embarked upon exactly one year prior. Once again I failed to record the whole presentation, but below is a Microsoft Sway slideshow with Spanish captions. (Click the full screen icon in the upper right corner of the presentation to enlarge, and click on the slide titles for the full captions.)
