At first glance I see a featureserver issue -- if you try the url that gets loaded initially (I just checked the firebug console), featureserver returns an error: http://69.59.158.11/featureserver/featureserver.cgi/parkinfo_google?format=json&maxfeatures=50&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&SRS=EPSG%3A900913&BBOX=-40075016.6784,-40075016.50840001,40075016.6784,40075016.8484
I note if you remove the bbox parameter from the url featureserver works fine. I also note someone else had a similar problem the other day on the FS list, but I don't know what happened with that. I recall he also didn't have simplejson installed. Can you install that, and ensure you are using the latest featureserver trunk? -Josh PS - you may wish to use polygons instead of multipolygons, since featureserver does not support the latter (though I don't think this is the problem at hand here), and if using the latest version you can also put 'attribute_cols' in your config to limit the field results - for example you may not need your original the_geom column being returned...
