DOWNTOWN LOS ANGELES — Just in case you ever need to know, the new Metro ticket machines now in place on pretty much every Metro rail line except the Red Line will take a maximum of thirty coins.

When you do, however, put your thirty nickels in only to find out it won't take any more you can simply push the cancel button to be given a shiny dollar coin and two quarters.

Need quarters for laundry day? Just spend a little time with the ticket machine (preferably at an uncrowded station). Put in fifteen nickels, hit cancel, and get three quarters for your troubles. Perhaps there are better ways to get quarters, but you never know when this might come in handy.
