Yeah, this sounds like a great trip. Good ST and options for longer rides. Zipping through wooded ST is pretty cool, something we don't get much of here. Even Mt Pinos isn't wooded anything like trails I have ridden in Utah with aspens just hugging the trails. Oregon pines, oh yeah, I can imagine it now. Like some of the riding in the Sequoia's or Hume Lake area.
The bummer is in the details:
Doesn't really sound like they cater to you outside of food and guides.
You need to rent or bring up your own camping gear.
I assume they don't set up and break down your camping gear every day then.
All in all it sound like fun tho
