A bit of a hack.
Thanks to an answer in the gis.stackexchange.com, I was able to contact the owner of a web mashup (driven by a google spreadsheet) who created an KML export link.
Copy/Pasting this link into the search box in Google Maps on my droid displayed the rest areas on the map.
There's a limit to the number of points the map will display out the KML, so if you are zoomed out too far, you'll only get a cluster of points. So make sure you are zoomed in close enough--having a few states visible should still work and be no problem.
When the map points load, the extent changes. I guess it's to the extent of all the points that were loaded from the KML.
