Hey Spana - this ones for you If you have Mailing lists of Senators, Colleges, Associations, Newspapers, etc anybody else in the US, UK elsewhere, give them to me ? Below is a condensed version of the letter i am forwarding. Please forward it to your friends. " A boycott of the games would be unfair to the athletes who have trained 5-8 hours a day for years. Yet having the games in China would be blood on our hands. But there is a way Let the Organizers, Media and the US take the first step by suffering a little bit, all for a good cause. The ENTIRE games program should be shifted to small viable stadiums in the US. In 4 months it will not be logistically possible to have a proper Olympics with crowds, sponsers and media. But the Games can go on, the athletes can give their best performances. All influential countries can pledge their support to this plan in April, May and most of the other countries will follow suit by July. We have 4 months, enough time if we act fast. Please make it possible. We must have a soul. The 2008 Olympics which will be remembered for perpetuity as the real soul of the Olympic Games."

Roughly 50% of the volume of good agricultural soil can be pore space -- the spaces between solid soil particles. These spaces will be filled with either water or air. The factors that affect the amount of water or air in those spaces include: 1. Depth to the water table. The closer the water table is to the surface, the more water is likely to be found in the soil. 2. Diameter of pore space. Because of the attraction between water and the surface of the pores, small diameter pores will hold water more strongly than large pores. (Think capillary action.) 3. Continuity of the pores. Greater continuity of pores means better drainage, and less water in the pores. 4. Precipitation. Obviously the more precipitation, the more water and less air in the soil. 5. Evapotranspiration. The greater the rate of evapotranspiration, the more air you are likely to find in soil. 5. Landscape position. Soils on hill tops and hill slopes will have better drainage than soil at the base of hills or soils in topographical depressions. The draining water needs a place to go.
