There's some in Colorado and I think washington state park or some shyt. I'll try to find the videos.
I started seeing these about a year ago or so and then all the YouTubers started getting their devices to showcase to their channels. There's a couple of companies that make'em I think the hypershell.tech might be the best ones or best/most advertised ones.
I even sent my boy a link like 8 months ago to those.
A good chunk of my algorithm is hiking/hunting/camping and random gear and fads come in and out. Like before these legs came in, everyone was all about trekking poles.
