There's a pocket in the suburb that I live in that has quite a few American families, with kids.
Halloween goes nuts in those streets, heaps of decorations and everyone gets into the spirit. My kids are joining the marauding herd tonight.
Good thing is, the kids put in an effort and dress up really well, not like when two kids arrived at my front door still in their school uniforms and said 'Can we have some lollies'.
