Simple execution. One nitpick though -- there's no way to get the final half dozen stores to show up because those cities never pass the top of the viewport (at least on my machine).
Same here. (I agree though, elegant execution.)
Only just noticed David posted my side-project on here :)
I thought I'd addressed the problem of making sure every store gets mapped. Thanks for the feedback though, I'll see if I can put in a fix soon.
