To paraphrase a saying, those who forget history are doomed to repeat its failures ("City eyes two-way traffic on St. Paul and Calvert streets," June 11). Before spending money on a study to convert Calvert and St. Paul streets to two-way traffic, I would suggest Baltimore first examine the studies done by Henry A. Barnes, the city's traffic director, a number of years ago when the streets were two-way back in the 1950s.
