Did you get it right?
The two covered-bridge picnic panels contain five visible changes.

The Answer
The correct answer is: five changes involving the bridge number, thermos stripe, picnic basket handle, fishing bobber, and creek stone.
Here is why
- The bridge sign changes from 7 in panel A to 9 in panel B.
- The thermos stripe changes from red to blue.
- The picnic basket handle tilts differently.
- The fishing bobber appears in panel A but is missing in panel B.
- The large creek stone at the lower right changes shape.
Why people miss it
The people and bridge pull most of the attention, so the smaller picnic and creek details are easy to overlook.
