Google Earth: Finding a Needle in a Haystack

Leave it to my brother to find something like this with Google Earth.

Step 1. Launch Google Earth.
Step 2. Find Portland, Oregon in the United States.
Step 3. Zoom in so you can see something like the image below. You'll want to look north of the Portland/Vancouver area where you'll find a river branching from the Columbia River.
Step 4. Zoom into the area of the branching rivers.

Step 5. Locate a skinny brown line representing a railroad track crossing from the wetland in the south to farmlands in the north. Look for a little bridge that spans the river you found in Step 3. Zoom into the bridge.

Step 6. You'll see a little smudge that looks like a blurry 'T'. Zoom in on that 'T'.

Voila! Aerobatic airplane in action. It turns out this guy regularly practices his aerobatics near the Ridgefield Wildlife Refuge.
