Dr. Bob’s Puzzles: HH2017

Four puzzles with gentle hinting to accommodate puzzlers of all levels. While the text suggests 3 hours, I expect the fastest solvers to finish in under an hour and those that wish to take their time to take 3 hours - or three days if you want to take breaks between puzzles.

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/color (ideally) printer).

Also, do not hesitate to use the internet as a resource.
