In "Town Fair", episode 106, we learn that blackberries are Moose's favorite.
In episode 106 we see Moose's kitchen for the first time. This location is very close to Moose's kitchen in the books.
The Town Fair location in episode 106 needed to be very specifically laid out in order to support all of the action. Despite the work, the senior location designer, Stephanie Duncker claims this was her favorite location to design.
Episode 106, "Town Fair" has the most secondary characters of any of the shows, coming in at 87 designs. Many of these are designs from other episodes (known as re-use incidentals) but many of the characters needed new outfits, to fit into a 'Fair Ground' setting.
Nineteen original location designs were drawn for "Town Fair" in episode 106. That's a lot of line mileage.
