@porfirio: Thanks a lot for trying it out. We're currently pulling in data from various sources like Foursquare, Google Places, etc. -- but we do add unique stops as well. Currently we've filled out unique stops for the PNW (since we're based here), but CA is definitely one we'd like to tackle soon.
First page of results. LA to SF. Next page includes "IN THE MIDDLE OF F#%~*?¥! NOWHERE!!! (Farm)"
