Cookies to remember states/countries?

I'm living in Kentucky and refreshing this page every day - it helps me handle going to work.
I was wondering if you could leave a cookie to remember what a user sets it to be, and then a reset button to clear it?

As a stopgap, you can bookmark the page, since the URL changes according to the displayed data. For (only) Kentucky, here's the link.

Adding more states or changing parameters also changes the URL, which means you can bookmark several preferred views.

I thought about the issue for some time aswell. The solution of MrSpiffyClean works fine but is not as simple for the average user as cookies would be.
