Read up on the Arlington ISD. Because some schools fall below what many parents find acceptable they allow in district transfers. Problem is these must be done at a certain time every year and for next years allotment it has already happened. The parents take off of work for a week and camp out in the Admin's parking lot in "line" for the entire time waiting for the time to open for them to ask for a transfer. There are only a few spots open for those wishing to apply for a different school than their neighborhood school and this is why they camp out for a week or more to be able to be first or close to the front. It isn't high school that is the problem but elementary schools.
Here is one news story about these transfer camp outs:
