I know you (solo) rider

Cool, where can I find this meet up thread?

To organize something like that, you would want to arrange to drive in with some others in your ticket level so you can camp together, and share prepared packing lists to avoid the consequences of two jars of mustard.

To go unorganized, pack extra stuff to share and most likely people near you will be doing the same. You may find the neighbors want to set up a communal site. I doubt anyone will sign up to share a tent but you might get lucky once you're there, if you know what I mean. Once the coolers start emptying people nearby may want to combine or at least split a bag of ice.

But my suggestion is, don't overthink it. Show up and roll.

Oops, I meant sharing a shade tent! Sharing a tent would be odd!

Do you have a Forest Camping pass?
