Gone Camping

Four friends spend weeks planning the perfect lake camping and riding trip. 

Two days before the group is to leave Rob's wife puts her foot down and tells him he isn't going. 

Rob's friends are very upset that he can't go, but what can they do. 

Two days later the three get to the camping site only to find Rob sitting there with a tent set up, firewood gathered, and supper cooking on the fire. 

"Dang man, how long you been here and how did you talk your wife into letting you go?" 

"Well, I've been here since yesterday. Yesterday evening I was sitting in my chair and my wife came up behind me and put her hands over my eyes and said 'guess who'?" 

I pulled her hands off and she was wearing a brand new see through nightie. She took my hand and took me to our bedroom. The room had two dozen candles and rose pedals all over. She had on the bed, handcuffs and ropes! She told me to tie and cuff her to the bed and I did. And then she said, "now, you can do what ever you want." 

So here I am.

Air pollution control district

In 1947, the Los Angeles County Board of Supervisors established the first U.S. air pollution control program by creating the L.A. County Air Pollution Control District. It responsed to the serious smog in the city on 26 Jul 1943 when a noxious haze of smoke and exhaust fumes reduced visibility to under three blocks. From Oct 1943, a Smoke and Fumes Commission studied the problem. It named many cause: locomotive smoke, diesel truck fumes, back-yard rubbish burning plus the mountain topography, stagnant winds and atmospheric temperature inversions. On 31 Jul 1954, a six-year research program reported that the smog was caused by the chemical reaction of sunlight on auto and industrial emissions. London's killer Great Smog on 5 Dec 1952, led to the Clean Air Act of 1956.«[Image: The first recorded photograph of LA smog, 26 July 1943]
