I can't find a simple map that shows rest areas on I80 from Iowa to the West Coast.  It seems like it would be so simple to make a map showing the rest areas and the mile marker for the rest area. 

However all I find are lists and lots of text. 

When you're driving it would be handy to simply note your current mile marker and see where you were in relation to the rest area.  Sometimes you want one because you just need a break and sometimes you really need one!

If anybody knows of a map that does what I want can you please post a link?
