For those of you with 8 year old children, do you still have your LO ride in a booster seat in the vehicle? My oldest son is 8 (will be 9 on Oct 1). He weighs just 60lbs & is what I'd consider average height, so I still keep him in his booster seat in the vehicle (except for the rare times MIL rides in back seat of our car with the 2 boys. There's no room for her + 2 booster seats). I believe it's age 8 you can have your child stop riding in one or it's based on height/weight as well. I'd prefer to keep my son in it for a while yet, until he gains more weight.
