We dont like one-way streets Highway planners decided to make a main street in West Lafayette, Indiana, a one-way street. Th e Lafayette Journal and Courier took a one-day poll by inviting readers to call a telephone number to record their comments. Th e next day, the paper reported: Journal and Courier readers overwhelmingly prefer two-way traffi c fl ow in West Lafayettes Village area to one-way streets.
