Yep, thought of that

Here is the email I sent to my boss when he asked me to look into it:

Seems straight forward.

How many dealers?

What about the granularity?

This is based on the center of the zip.

Does this need to find multiple dealers in a single or a couple of zips,
which would possibly send a person to the wrong area?

Consider natural barriers like rivers too...

If I were to use something like this in the DC area, I'd want to consider that there are only a few Potomac river crossings. Thus a Lat/Long bee-line distance may be quite short, but the actual distance may be much longer due to the necessity of going across a major bridge.

If you were looking for the nearest McDonalds, it wouldn't be an issue. If you were looking for the nearest IKEA, it would be.

There's probably not a simple way around this problem (unless you're tied into MapQuest or something similar), so giving several possible answers and letting the user choose is probably the most reasonable approach.

Cheers,
Scott.

As the bird flies

That is the directive. So rivers, etc, are OK

You do something clever with the number of results.

If you figure out (say) 10, then stop displaying them once the distance gaps get suddenly a lot bigger. So if someone is real close to 2, moderately close to another 3 and quite far from the next, they see 5. But if someone is moderately close to only 4, they see 4. And if someone is quite a ways from 3 and quite a long way from the next, they see 3.

Too confusing

I can imagine the tech support calls when people get a variable number of responses that do not seem to correlate to exact distances.
