In a 1965 episode of Exploration Northwest, Don McCune chronicled the Yakima Ridge Runners trip over the Naches Trail, comparing it to the first pioneers crossing of the trail known at that time as the Meeker Trail. Linda McCune has allowed me to make a couple short clips of that episode.
Here's clip one as the jeepers prepare and reach the eastern start of the trail. http://www.youtube.com/watch?v=gycvwTXgZ9U
Here's clip two as the jeepers negotiate down the western steep slope of the trail. http://www.youtube.com/watch?v=GR2UzzF6WI8
You can learn more about the episode and other jeep related episodes of Exploration Northwest from this blog post http://www.ewillys.com/?p=603
Finally, Linda has another jeeping episode, but she needs to assemble it. I'm not sure what the episode is about. So, I'll be checking back with her in the future to see if she's made any progress.
