The database is definitely incomplete - I have a ton of work left to do.
There is also the problem that just because a certain produce item is being harvested within x miles doesn't necessarily mean that produce is available at local stores, and vice-versa.
My hope is that if I can get some early adopters, I'll be able to concentrate improving the data in a smaller number of targeted areas. This is the first time I've shown the site to anyone, so I'm hoping I can get some feedback to make the most effective improvements first.
