There is something on the map to the right of the line for # 4 about halfway down the fairway. I was assuming that was the playground. Whatever that is, it is in the middle of the #4-#5 fairway and will get hit with discs from people playing both of those holes as well as by errant shots from #3.You can't see the playground in the middle of 4 and 5 cause it hadn't been built as of the time of the pic.
The pin for # 3 will have shots thrown by people playing #5 land in the circle if it is really that close as well. Holes #3-#4-#5 are a really bad design even if they were the only things around there; add in the roads and whatever that building is to the equation and it's a horrible design. If there is a playground right there that can be hit from all three holes, the design is really something from a safety aspect that should never be allowed to happen.
