Weather: another beautiful day.  Again, wind and showers to the south of us at the end of the day.  People actually complained (a little) of being hot at lunch.

People: Chris, Steve, Tony, William, Antonio, Gary, some help from Elise.  Two people from NOAA were working on "Tilden's tower", and Aaron showed up from UND to deploy some of his stuff.  Erik visited again.

Tower tasks:

• Leveled and tensioned all 35' towers
• Placed 3 4' screw anchors, 1 for each inner guy point an 2 for each outer guy point for the 20m tower.
• With these anchors, popped the c tower up to 60'.  One more section to go!

Other tasks:

• Wired AC power to all towers.  Verified that at least the d and ue DSMs were working.  This also got our internet working – Gary was able to connect his laptop via wifi.
• Installed soil sensors at d.
• Prepped the radiometer boom.

Summary: We're pretty far along now.  Towers almost complete.  Power running.  Internet running.  Now we just add (more) sensors, data systems, and cabling...
