Our National Parks are overcrowded. Here's how to fix that.

Yellowstone and Yosemite will continue to be overcrowded unless officials implement a reservation system at more national parks and hire additional staff to handle the influx of visitors, federal lawmakers said Wednesday. 

Those were two suggestions made by Angus King, a U.S. Senator from Maine, during a Congressional hearing about how to alleviate overcrowding at the nation's 423 national parks. King also floated the idea of steering people to the "lesser known jewels" in the parks system, like Big Bend National Park in Texas, as well as restricting the number of cars the public can bring to a park.  After months of lockdown during the pandemic, Americans are now flooding the national parks, leading to 4-hour wait times and increased litter along park trails. King said Wednesday he believes visitors are now "loving our parks to death."
