I will be at a solar eclipse festival where there is no cell service (it's waaaaay out in the boonies). I would like to distribute a viewing guide (PDF) for attendees to view on their mobile devices.
What would be the best way to do this? Can it even be done? Can I create a mobile hotspot from my Android or Windows device even though there is no cell service? If so, can I create a simple page to allow them to download the document? How would I do that?
