Elevation would be nice for Google Maps. My primary trail I ride (Hennepin canal bike trail in Illinois, 60 mile long trail) isn't loaded on Google Maps yet, I've reported it.
Which brings me to my point of posting. Those of you not using Google Maps, it would help them out alot if you would at least open it up and try your commute, and report to them the problems in their reporting. They cannot possibly test everything and know every nuance of every city, but with enough reporting by the community, they will get it right. The Quad Cities (just next door to me) are trying to do this, twas an article in the paper a couple weeks ago to go along with the report about Google Bike Maps.
We can all do our part.
