I lead a club bagel ride (about 15 in the am. It was mostly fast guys who wanted to go farther, so I told them they were were on their own. I bought a New Camelbak last night, so tried it out and scoped a ride I will be leading on 7/1 to an air museum(wen by Corsair drive...). It all worked out OK. Typical Inland Southern California June day (Hazy with temps in the 90's)
