I think school choice makes the most sense. Not everyone would go to the school closest to thier house.

For example if one school happens to consistently produce students with bette SAT/ACT scores, I could see sending my child there even if a closer (not as hilghly ranked) school is available. I'm sure other factors such as Drama programs (which was important to my oldest) may be important as not all schools offer a wide range of Drama. Obviously too, I think sports, Alumni, closeness to friends/after school care etc. are all factors that would impact choice.

I believe if a community desides to self-segregate, then it should be o.k. as long as it's truy a choice and no pressure put on peole to decide based on race
