Yeah I remember when he put that route up. Pretty rad. A few of us tried it a few times and couldn't see it. I don't think any of us went that far out to the left side.
Josh has a number of unrepeated routes. Mostly Scott Cosgrove testpieces. Perhaps Chris Lindner will go on a quest, and do some more?
That's a good video clip. When Lindner was a kid doing hard routes we used to tease him, saying how all those holds would just keep getting smaller (as he got bigger.) Looks like we were wrong.
When I saw your thread topic I thought I was going to see Mike Paul doing Stem Gem barefoot facing out, playing air guitar. Ever see that one?
edit: What do you grade a Joshua Tree route at which took 20 years to see a second ascent even though it is in a prominent location and put up by a real player? Hmmm.
There is no grade, just do...
