Everything appears to have a name and is either a school or a park (and contains appropriate attributes for that).

Earlier today I opened my data file and did a "simplify" on all the polygons.  That really trimmed down the number of points.  I did a couple spot checks to see if this adversely affected the accuracy of the data and I didn't see anything that really stood out as being problematic.

If there are no other objections or input (I haven't heard any new input since last Friday) then I'll start uploading these polygons (manually using JOSM) later this weekend.  Any duplicate areas or POI will be merged or will be left alone if the data looks to be of better quality.

Thanks for everyone's input.
