I walk past Reston's Dogwood pool every day. The Reston Association has a proposal to redo the pool and its surroundings which is going through the hearings process. As part of that they've had a crew string white tape through the nearby trees, I guess to outline the area where trees will be cleared. What the crew does is tie the tape around one sapling (2-3" at shoulder height) then run the tape to another sapling and tie again, repeating the process around the area. Unfortunately, every time they run the tape they make it taut between each sapling. When they're through everything looks fine and neat. As time passes though, and the wind blows, and the saplings start to move, and they move in different directions, the result is the tape is first stressed and then it snaps. So a month later there are just a few segments of intact tape, but most are broken. Another month passes and RA sends the crew out again to remark the site.
Sometimes in life it's important to leave some slack.
