This is a clip from an old 8mm movie that these guys shot of stunt action on highway 99 between Eugene and Junction City, Oregon.
Just in case anyone thinks that stunt riding in traffic is a new thing!
This video is copyright Oregon Vintage Motorcyclists, and C.R. Saville.
Mr. Saville is one of the riders in this clip, and he's now almost 100 years old.
