I could be wrong, but on a smaller scale, isn't something similar taking place, at least in Champaign, with the elementary schools? When we first moved here, we found out that you have to select your top 3 elementary schools and you would have to be accepted into them because they were trying to even out racial concentrations due to one mother's complaints. As a consequence, my brother goes to a school that is nearly all the way across town when there is one a mere 5 minutes from our house.
