[Geowanking] California roads data

[Jennifer Strahan]

Hello,

I know it's a long shot, but I'm wondering if anyone knows of any 
free sources of detailed roads data for California that is better 
than Tiger.  Or, are there any WMS services out there that offer 
better data?  We are a non-profit organization who is publishing an 
interactive map of public parks in the state.  We've tried overlaying 
our data on top of a google basemap using OpenLayers but the result 
is confusing.  Ideally, we would like to create our own custom 
basemap.  Tiger data will suffice, but it would be nice to have 
better data.  I don't suppose any of the large data organizations 
such as tele atlas ever offer low-cost licenses to non-profits?

Any suggestions would be appreciated.

Thanks,
Jennifer
