Mid 60's my brother is working in a bank and is asked to work one night a week at the local track. His job there was to calculate the show prices. The family went to check out what was going on and never looked back. Track record at the time JB Senator 2:07 driven by Peter Miller. The mutual tickets were all preprinted and a daily double ticket required the first half winners to line up again to exchange their ticket for a second half ticket.
