I really enjoyed this episode. I have complained about how these are called "adventure" labs but there is not usually much of an adventure in walking around looking at building and historic markers. And lab conjures up an image of hands on experiments, not your ability to count fence posts or read plaques. I also love that you tried to make your labs friendly to people with disabilities.
What confused me, how did you add code into each location so that it would be interactive with games? Did you just enter a block of code instead of text in the location description?
