I place signs/buildings to make jokes in my township. For instance, I would prefer to place the neon cow sign to the right of the Fast Food Restaurant, so the cow points to the hamburger. However, since we only are permitted one sign per township, I must move it to where my Crops & Factories are located (to simplify collecting my items for other townships' Plane/Train/Zoo requests). With this restriction in place, I place my township sign on its own island, just large enough for the sign to snugly fit.
