9 batteries in 25 minutes - a new personal record

I went for a walk at lunch Friday, over to Towson and Hudson Trails shopping for eating utensils (found a foon for $2, not a spork, not a spoonfork, not a forkspoon, a foon).

On the way back to the office I decided to vary the straight-ish line I took to get there, and look for dead batteries in parking lots around Towson.

In an April blog, I had noticed how much battery hunting was like fossil hunting, or archeology ("first 3 were several feet apart, at the downhill side of the Middlesex shopping center parking lot, like dinosaur fossils collected at a flooded stream site") and this expedition was very similar. Here's the photo file log, showing the shots that I took, and excluding dupes:

I used NetPBM tools to mosaic these into a 20K JPEG file.

And then Xpaint to show a closeup of one of the nearly buried specimens.

The ones wedged under the concrete parking barriers were the trickiest to find, and the shots are not so great since they were usually in shadow. I think the camera phone behaved adequately, though, despite my inability to see the screen in the bright sunlight.
