EX Wind Fence Status: Remaining 3-Old Fence Panels Removed, Compacting Soft Sand, Start Upgrade Installation

(CoreyG, MitchR, RandyT, JimW)

Previous work posted here.

Today started with Randy and Mitch getting the small green tractor to EX and then working on compacting some of the very soft sand around the wind fence (on the front side of the Wind Fence---closest to EX).

Started to remove the final 3-wind fende panels (of 6 total).  While driving the orange rental manlift (on the backside of the wind fence), it managed to get dug in some pretty deep sand a few times.  On the last dig-in, we kept the manlift here (dug out/compacted sand around it and focused work on the furthest away wind fence panel since we already had the orange manlift here).  The plan is to do everything for this panel location all at once:

  1. Remove old (crappy) hardware,
  2. Install better hardware,
  3. Clamp horizontal wires to the end/furthest pole,
  4. Start tensioning the 5-horizontal wires into place
  5. Install new wind fence panel

Today we made it to step 4 and did the 1st/bottom horizontal wire.  

We ran out of the thick wire, so the trailer was brought back to the Corner Station so the 1200lb spool can be loaded into the trailer in the morning.  Then will continue getting that 1-panel installed....and then work on getting the orange manlift unstuck.
