OR, you find a place that has multiple walls, adequately separated so as to count them as separate search areas. For instance, we went to the local Rec Center, which has several different buildings. We did the first search on the southwest wall of one of those buildings and the second one on the northeast corner of that same building. Hides 3 and 4 were on the southeast side of a different building and on the southwest side of that same building (more on the west side than the south). We did them two and two, but could have done all four at the same time.
