Doing a search to find a particular specific fact may not be as easy as one would wish. Here's an example of how to find how many acres of cucumbers were planted and harvested for pickles (with a bow in the direction of Altus, Arkansas' pickle capital).
Then pick Crops from the first menu under Statistics by Subject:
Choose Vegetables, then Cucumbers, from the menus, and you'll get a list of data items that you can choose from. Mark the ones you want, then click continue.
