Day 2! Cool - upper 30's when I started riding, but was plenty comfortable after about 10 minutes. Came across a small, scattered pile of flat black (matched the pavement perfectly!) 4" jagged rocks on the shoulder of the busy road I travel - probably fell off some truck over the weekend and was swept / blown to the side. Saw it before I hit it, but not early enough to avoid it altogether. Took a pretty solid blow to the front tire. Fortunately there is no apparent damage and I stayed upright. Sure got my attention! Great sunrise brewing as I ended the ride, but I was a bit too early for the real glory. Once again, I'm wondering why I waited so long to start this...
