Here's two of my current favorites. The first one was taken this past May at the Indianapolis Motor Speedway. I just happened to be passing through on my to Canada on Community Appreciation Day - the Wednesday prior to the running of the Indy 500. Cost me $15 to run the track - I would have easily paid several times that.
The second was taken on the salt flats in Guadalupe Mountains State Park just of Highway 62 around midway between El Paso and Carlsbad, NM.
