Okay, I sorta got it to work... I'm not sure you can view this on the road unless you have the version with constant internet access. Even then, its not without flaws. Here's how I did it:
1. Load the .kmz file on your website.
2. From my PC, log into your Google account and click on Maps.
3. Enter the URL for the .kmz file in Google Maps and click Search Maps.
4. Save it to My Maps and you can see all the RoadFood flags now.
5. From the iPad, open the Google Earth app.
6. After it adjusts to your location, touch the Layers button.
7. Select My Maps and then My Maps Account.
8. Log into your Google account on your iPad.
9. Select My Account and then select View Data Stored with this Account (under Dashboard).
10. Under the uppermost, top menu, select More and then select Maps from the drop-down menu.
11. Select My Maps and then you should see the .kmz file listed underneath.
12. Select the .kmz file and the RoadFood markers should appear on a globe inside the sub-window. You can hide the left pane in order to see more of the map.
I tried viewing the map a couple of times, but I think it might be too much for the current version of the Google Earth iPad app. The reason I say this is because I can get all the way to the point of SEEING the markers for RoadFood stops, but when I try to click on one, the app shuts down and I have to start the process all over again from Steps 5-12. You could try restarting the iPad and try it again. Sometimes that refreshes the apps or something...
Guess we'll have to wait for the app to be a bit more robust before this can work really well... But, at least now we know how to view it on the iPad!
