This is a photo of my uncle Beto around 1946-48. Just Pryor to his service in Korea. He was a Golden Glove fighter out of Boyle Heights and would also fight on the Air Force boxing Team. Looks like he is on a 41 Indian Chief "Cut Down" these were the early days of chopping. Top photo is of either El Sereno Hills or Monterey Pass, both locations were used by local bikers for weekend Hill Climbs. Dig the dog bone risers and flanders bars.
