In today’s episode of Backpacker Radio presented by The Trek, brought to you by LMNT, we are joined by Danielle and Cassie, the hosts of the popular podcast, National Park After Dark. In this episode, Chaunce gets the lowdown on some of the most outrageous stories from the our beloved national parks, including the infamous cocaine bear, tuberculosis huts in Mammoth Cave National Park, the tragic tale of Ishi, the last Yahi, who emerged from Lassen Park in the early 19th century, and the night there were two separate fatal grizzly attacks in Glacier National Park.

We wrap the show with an opportunity to get paid to thru-hike (and consequently why you should be on The Trek's newsletter), cheap items that double as ultralight backpacking gear, my mediocre marriage advice, the triple crown of outdoor fears, and another listener offers a PSA on why you should probably not use dry ice for your resupply.
