We decided to explore an area of Baltimore that we were not that familiar with. The directions are minimal, other than just go. Some of the clues are intentionally misleading. Let me say dont take them literally. We were doing a brisk pace, and ended it early with about 5 clues to go, because it was getting dark, and the area we were in at that point was fine by day, but evening you may have to be a bit more cautious. They said it would take about an hour, NO WAY, unless you were familiar with the area. We didnt even know about the extra points, I discovered them halfway through, then realized you cant submit them unless you share on social media. The areas and trivia were interesting, but the lack of basic instruction and incorrect average time to complete was frustrating.
