Parcel data. WTF is that, you ask? It’s all the information associated with a particular parcel, or specific plot of land. ParcelQuest.com is the numero uno provider of all the up-to-date, accurate California parcel data anyone could ever want. Who would want to do that, you also ask? People who take geeking out about all things parcels to extreme (and disturbing) levels. They’re more than obsessed. And more than specialists. They’re obsesscialists.
