Bryan,

I am trying to set up a map to work with MyTopo maps, OSM, Google Terrain and
Google Satellite.  Will this work?  I have tried your code (inserting my own
MyTopo API key) but I get blank tiles on the MyTopo layer.  Could this be a
problem with the projections, which I admit I do not really understand?

Thanks,
Jennifer
