[BREAKING: As of 8:45pm EST on Friday, both the House and Senate had adjourned for the evening, meaning a federal government shutdown will start at 12:01am EST on Saturday the 21st.]
Chaos may reign for the thousands of visitors planning to take snow hikes, rock climbing trips and sightseeing visits to US national parks over the winter holidays, if the government shutdown goes forward at midnight on Friday.
Park conservation groups say it is likely to mirror past shutdowns – with confusion about which parks are open, closed facilities, a lack of protections for guests and wildlife, and many disappointed visitors.
