		+	===Post Trip Notes====
		+	* Need proper diameter screw for securing nuc to wall
		+	* took a bunch of photos that need to be uploaded to dropbox and then I can update the google presentation.
		+	* HMP155s
		+	** D site and C site lower units were too corroded to replace so only did tips.
		+	** replaced top C HMP155 with a new one.
		+	** also replaced a tip and HMP155 at B
		+	** replaced A lower HMP155 and moved it to the upper position.
		+	** Almost all S/N from units out there were sun bleached off.
		+	** Leveled all radiometer Domes and swapped out desiccant.
		+	** leveled A & C precip buckets (C was already level, A was off just a bit)
		+	** Replaced all SR50A Transducers (2 @A, 2 @ B, 3 @ C, 1 @ D)

I'm not sure what that was about. A couple potential alternatives might be read only OS / ram drive for logging as needed (though perhaps risky).
		+	* didn't touch any of the WS sensors.
		+	* downloaded data from all sites and there was data dating to 2016-2017 so good news as it seems the cardout instructions are working properly on all four loggers.
		+	* noticed the MD485 connection to grid site was loose / perhaps off so I screwed it back in but didn't test link.
		+	* the main good news is that since the cardout is working properly the real-time connection is less important. Just disappointing.
		+	* made good use of the ladder from the flux tower to get the 3.5m sensors fixed
		+	* replaced the antenna at the C site so hopefully will improve radio link.
		+	* For the record:
		+	** Flew in on evening flight.
		+	** next morning filled two daypacks for the day's work.
		+	** got breakfast
		+	** met up with UIC for safety training.
		+	** started walking to site around 10am.
		+	** Got back to truck at the end of the day around... 4:45 I think it was
		+	** A slightly less intense trip would be fly in on the morning flight, get the safety training out of the way and then still leave on the evening flight. Something like that schedule would allow for more miserable weather as we had fantastic weather (clear / sunny & quite windy).
		+	** safety training done the day before would also allow for an earlier start.

-** bringing a bit of electrical tape to seal these things up after sensor replacement
+* Level Radiometer
 * need to replace the network cable running from the computer to the network switch.  It cuts out with minimal bumping...
 ** I think I almost need to connect the computer to a screen to see where the hang up is if it indeed turned on so I'll bring my light keyboard/mouse and an HDMI to DVI cord.
 * label the computer
 * bring up the nuc plate and wood screws and other screw packet to mount nuc to wall
