Left Denver at 9am, to Morrison, Evergreen, and then up to Echo Lake. Around 10k ft, it started to hail and lightning, over the pass and stopped at the Mt. Evans Gift Shop on the other side to warm up with a cup of joe. Lots of bikers in there had the same idea. 30 min later, sunshine all the way into Idaho Springs, and then rain all the back to Golden. Sunshine the rest of the way back into Denver.
Pretty sure I hit every season on today's ride.
