The infrastructure of your parks, is your biggest on-going expense and will often determine annual profits or losses. Are you doing all you can to examine and invest the latest technology that will give you the best long-term ROI?
In the case of roads, your residents use them every day and naturally they will associate the condition of your roads with the overall quality of the community. Having good looking, high-quality roads will justify increasing rents.
