Attention shoppers: your next visit to the National Mall might come with a hidden fee, as taxpayers face a looming $20 million bill for a massive fuel cleanup under the iconic lawn. The decades-old underground fuel tanks have been leaking, and proposed cleanup plans could see your wallet hit through increased park fees or delayed maintenance on landmarks you actually visit. Don't let this become a "stealth tax" on your family's weekend outing. Demand transparency from the National Park Service on who fixes this mess before your dollars are forced to soak up the spill.
