The sounds of snowplows and ice scrapers through much of the country have been replaced, at least temporarily, by the sounds of race  cars at speed as the Amercian Le Mans Series Winter Test opened Wednesday at Sebring International Raceway.  New teams, cars, and drivers were ready to take to the historic 3.7 mile circuit which will kick off the 2011 American Le Mans Series and Intercontinental Le Mans Cup seasons on March 17-19.
