corsair... LOL! If I rode unsupported centuries a camelback would be a MUST! As it is I'm most likely gonna get one to do this ride... considering riding it... supposed to be a fun one! Sometimes, tho, it's just too dang hot to wear a camelback... I don't know how people do it! Of course, I'm talking about here in San Diego east county where it's 105 degrees throughout the summer... blech! Too, too hot!!! If I do this ride I'll have water in the camelback and Cytomax in the water bottles...
