8. Constant Up-Keep
Mount Rushmore wasn’t cheap to build, as it cost a total of $989,992.32 from start to finish, but it’s the type of gift that just keeps on giving. Every year the mountain has to be pressure washed to prevent nature from doing what it does best and cover it with life such as shrubbery, vines, small plants, etc. At least the cleaner has a nice view while they work, as the mountain is illuminated every night for at least two hours.
