From "Dodgers to help raise funds for Japan aid" by Ken Gurnick at Dodgers.com:
The Dodgers and NBC LA will hold a "drive-through" relief effort at Dodger Stadium on Tuesday to help raise money for the American Red Cross Japan earthquake and tsunami relief efforts.
Dodgers alumni and members of the NBC LA news team will take donations from 5 a.m. to 7 p.m. at the Dodger Stadium Parking Lot 1, which is accessible through the Sunset Boulevard Gate 1 at 1000 Elysian Park Avenue.
Cash donations and checks will be accepted. Checks should be made out to American Red Cross with "Japan Tsunami Fund" in the memo line.
UPDATE: From a Dodgers press release:
Donors who give $20 or more will each receive two tickets to an upcoming Spring Training exhibition game at Dodger Stadium.
