It will soon be hard traveling on most of the buses cruising the traffic-jammed streets of the nation's second-largest city.

The Southern California Rapid Transit District, hoping to discourage seat-destroying vandals, plans this summer to begin replacing cushioned seats in more than 1,000 of its buses with hard plastic ones."Unfortunately, there will be some reduction in comfort without a padded cushion," said RTD Associate General Manager John Richeson. Officials say it costs $400,000 a year to replace soft seats ripped up by vandals.
