The Schools file

I downloaded the Midwest schools file - it has many references to 'historical' schools - and, if one has speed/proximity alerts set, you get alerts for schools that are not even there anymore. And, only one of four schools I go by frequently had accurate coordinates in the database - I took the original data and plotted it on-line and found them to be several blocks off - entering better data from geocoding the school addresses and updating the csv file made alerts work for those schools. I hope others have better luck with the schools file(s) - I'm going to nuke it from my GPS for now.
