We are going to Disney in March 2002. We have two children, who will be age 7 (70 lbs) and age 4 (40 lbs) when we travel. I had heard that beginning January 2002, there will be some change in California law increasing the age/weight for which car seats will be required. Do any of you know anything about what the requirement will be? I asked the car rental company but they didn't know. Thanks!
