Take an Ego Trip without Leaving your own Land
"By clearing forest so that a pattern would be visible to landing aircraft, a landowner outside Austin, Texas, created a target that is also useful for evaluating spatial resolution of astronaut photographs. The forest was selectively cleared in order to spell the landowner's name 'LUECKE' with the remaining trees. According to local surveyors who planned the clearing, the plan was to create letters that were 3100 x 1700 ft (944.9 x 518.2 m).
