As found, neither CP3 nor CP4 showing vapor at exhaust.  CP3 had frosted exhaust line (typical for environment, shaded).  CP4's exhaust line not frosted (typical for environment, in sunshine).  As previously mentioned by Dave B., the T/C wires fed into CP4's exhaust have an excessive loop which will get snagged by tumbleweeds eventually -> Manually overfilled CP4 by opening its LLCV bypass valve 1/2 turn -> LN2 at exhaust outlet in 15 seconds.  -> Manually overfilled CP3, by opening its LLCV bypass valve 1/2 turn -> LN2 at exhaust outlet in 15 seconds as well.  Leaving CP3 LLCV %open for "others" to fiddle with remotely.

Bottle pressure of UHP N2 bottle used to slightly pressurize CP4's clogged sensing line (20 psi) now at 1000 psi.  

~1340 - 1345 hours local -> Kyle in and out of LVEA

Rotating shaft vacuum pumps ("my girls") used for PT180 experiment are cool and quiet ("and happy - a man knows these things!")  No sign of gauge drift at this point.

1410 hrs. local -> Kyle leaving site now.
