Only around 10% of America’s original fire towers still survive today, but if you’re itching for a Kerouac truth-seeking adventure, you might be interested to know that you can actually stay overnight in one of the surviving towers. https://www.messynessychic.com/2017/05/31/secret-summer-cabins-in-the-sky-for-the-great-american-road-trip/
@estherschindler We have a friend who goes and stays in one for two weeks every summer as a fire spotter volunteer.
Still in use but I wonder for how long.
