Super Camel Back

Someone please design for me a large plastic bladder that will fit into a Bob Yak Trailer just so. The bladder may have to be made so that it is double walled, or more like a bladder in a bladder so that air pressure can be put into the outer bladder and water in the inner bladder. That way a constant pressure will force drinking water through a tube to the outlet, which will be where the cyclist, in this case me, can have enough water to last for the 700 mile ride across the vast Texas desert. If nobody can come up with this design by the middle of September, I may have to invest in a regular camel back. Just a thought

Six more days until the longest day of the year gets here. Hip Hoorah. Well, I suppose that all the days are the same length, but the longest day of daylight is coming.
