[AZ-Observing] Re: 5 Mile Meadow

AJ, you are exactly right on the temperature variation. Thad and I both had
high-low memory thermometers and he got an overnight low reading of 25
degrees out into the meadow and I got a 32 degree low reading under the
trees.

On getting cold in sleeping bags, it should be kept in mind that ratings for
sleeping bags are typically for northern, cold-weather people who are used
to sleeping "cold." We warm weather souls from Arizona need more.  The
sleeping bag I used is an oversized bag rated to 0 degrees and it was just
right for the five mile meadow trip and would have worked for me down to
about 20 degrees.  I also have a 30 degree mummy-styled bag which is only
good to about 40 degrees, if that, and not nearly so comfortable and roomy.
It got left at home. AJ, you just need a decent 0 to 10 degree bag and a
good fleece cap and you would sleep fine.
