Dr. Bob's 2020 Online Holiday Puzzle Hunt

This year's hunt is themed around 2020! There is not a hint of holiday theming - but, I'm keeping the title for legacy sake.
Puzzles have gentle hinting to accommodate puzzlers of all levels. It is worth noting that those who have played previous Holiday Hunts will find that this one is a bit longer (on par with 2018 and 2019). That said, while the text suggests 5 hours, I expect the fastest solvers to finish within a couple of hours. The hunt is set up to accommodate those that wish to take their time and take breaks between puzzles. It is also conducive to working with teammates (albeit, online in creative ways).

To do this hunt, you will be directed to URLs of PDFs that you are expected to print and solve - so, before playing you should be sure you are appropriately equipped (computer/internet). Having a printer will help, but is not required if you have other ways to mark things up on your computer.

You should also either have access to the Pandemic board game board... OR be able to find a high quality image online - here's one that might help: http://www.drbobspuzzles.com/events/ohph2020/PandemicMap.jpg

Also, I expect most will have to use the internet as a resource. This is totally fine! For example, there are many pieces of information that I wouldn't consider "common knowledge" and will be required to solve some (if not all) puzzles.
