I finished my northbound JMT hike a couple of weeks ago. For those people like me that enjoy watching backpacking videos on YouTube, my videos can be found at the link below. I've been posting one 5ish minute video per day of the trip. I'm up to day 10 so far. There are also some gear and food videos related to the trip on my YouTube channel as well.
Here is the link to the day one video. I start at Cottonwood Pass campground and head north towards the JMT.
