@Setanta,
Sorry about the scared little girl dog but otherwise, congrats!
Yeah, ours was well-timed -- hit at about 6 PM, temperature plunged, it stuck around drizzling until sundown, and then the sun was, ya know, down, and it's been cool straight through. Just starting to warm up and get sauna-y now.
Holy crap, it was 73 when I checked about 10 minutes ago, already 77. I was planning to do some yardwork before it got hot, better skedaddle.
