1969. my best friend had just turned 16 and his dad bought him a brand-spanking-new, assembled-it-himself-out-of-the-crate (he was a part time parts guy @ local honda shop) cb160. the first saturday morning that he had it, he came by my house so we could go riding with a friend who rode a yamaha 80.
he picked me up ~7am and we headed off ... me in jeans and a t-shirt, my friends in jeans, sweatshirts and levi jackets. we cruise around town for a bit, then decide to head over the bay to a town called port costa. this involved riding near the waterfront, over the carquinez bridge and on the other side of the bay ... all of which, it turned out, was blanketed with to-the-deck fog. a few seconds into the fog and i'm starting to feel the damp on my skin. an hour later and my skin is blue, lips and teeth are chattering and it's all i can do to hang on to the seat strap. "no, guys, i'm ok ... let's keep going ..."
in < an hour i'm a popsicle stick, so we head back home ... that's when the deep freeze set in.
we decided to grab a bag of burgers & fries at a local place to warm up. problem was, i couldn't hold the food to eat it ... i ended up with coffee and sitting in the sun for an hour or so just to warm up.
(the next year the guy with the yamaha 80 got a cb750, my friend upgraded to a cl450 and i picked up a cl77. my then-best friend and i are still best friends and we still ride together all these years later.)
