Yeah looks like there were a few bad geocodes that I didn't catch. paulitex's idea further down about a standard format for these things would be really nice to see b/c parsing out the locations in some cases was kind of a mess.
I recently did a project with just geocoding in Ontario and it took a while to fix all the various cases for the 600+ volunteer-entered locations. Bonus points: only some (and different) geographical information was available for each address. Postal codes/zip would be ideal for this.
Geocoding problem?
