We left Phoenix yesterday afternoon in 108 degree heat and got out of the van 2 hours later in 73 degree cool. 35 degrees!! And I can assure you, it makes all the difference in the world. Last night we slept with the windows open and the temp dropped to a glorious 59 degrees. Now THAT's good sleeping weather right there!!! Looking forward to doing a whole bunch of nuthin' on the porch today. Later.
