You’ll need some trad gear and long slings or bits of static rope for most places (someone please jump in if I’m wrong). There are a few climbs per crag that will have bolts at the top but it’s not the norm. By ‘at the top’ I mean ring bolts placed close enough to the top of a climb that you can use quick draws of shorter slings in your anchor setup.
You’ll also need some funky Aussie inventions called bolt plates as you’ll find a lot of bolt heads without bolt hangers!
And as for our trees . . . not good for anchors (I’m thinking of the large oak trees in New River Gorge, etc.).
Also watch out for hoop snakes and drop bears.
