does anyone know where to find them?
Normally, your best bet would be Roadracingworld.com...
...but I went there tonight and noticed they have the F-USA qualifying results from today...but no results listed from Friday. They might post them later, so check there tomorrow.
Looking at some of the other info from the 600cc races I would have to guess that Himmelsbach would have been right up there. Provided that there were no other issues.
