We just drove by and all the sites are taken!
If you go to the right, it says trail of time. Follow the road to the top. There are several sites up there with fire pits.
Not sure about having fires outside of a burn pit but as you come into the area if you stay to the left you'll be on the main road. It's well groomed dirt. They'll be spots along there.
Yes, no fire restrictions. If you come now there is still places to park. Go left at the fork on the south side of the interstate. There is a group area that is open.
