27: sled-1, Site 1, Sat 11-Oct-1997 06:17:15 GMT, Sled-1 hinge broken
The lid on sled-1 was caught by the wind which sprung the hinge.
This happened roughly on 10/7.
A rope or strap is now needed to hold it open.

The exhaust stack also had some of its inadequate rivets pop loose
although it seems to be holding OK.

BEWARE not to push it over and have it flop enough to smash it more.

28: sled-1, Site 1, Sat 11-Oct-1997 06:20:32 GMT, Sled-1 GPS wire cracked
Note the PVC insulation on the GPS cable for sled-1 cracked in the cold.
The sensor is still working.  This happened roughly 10/7.

During site visit on 4/6:

~00:15 2 Solar Panels installed.
	One on each side of box.  The box appears to be oriented roughly E-W
	so one will get minimal sun.   The other is facing relatively deep
	snow (2-3') in front of it but it should still get some decent exposure.
	Verified PV/cables.
	Only mounting arrangement of the panels and cabling will require that
	they are removed during transport because of clearance with outrigger
	brackets.  :-(   Fortunately very easy to do.
	Observed power monitoring system still providing reasonable values.
	(saw 'Vteg' w/ PC showing 16.7 during sunny period: good sign it's
	seeing the PV.  Stay tuned.

	Sled Venting:
	2" Cable access added to rear of box and about 1' from the floor.
	1 Solar Panel covering the louvered vent.
	Added 2" passive weather-head vent with heat motor to lid over
	TEG cooling fins.  Unable to fully tighten the PVC parts on this one.
