IN PRAISE OF BEACHFRONT TWISTERS. A proposed upgrade of Navy Pier that includes a roller coaster is coming in for some criticism. Noisy? Lights? Looked at Lake Shore Drive or Wrigley Field lately? Lake Michigan could use a roller coaster at water's edge. Let's call the roll on the other Great Lakes ... Cedar Point's Magnum and a few of its neighbors ... Sea Breeze's Jack Rabbit ... shed a tear for Crystal Beach ... the Greyhound at Bay Beach is long gone. The situation on the Atlantic, Gulf, and Pacific coasts is not much better.
