Rode the MTB up Mt. Hamilton Rd. from San Jose, then made the short hike to the lookout tower on Copernicus. Hung around at the summit for a few minutes taking in the various views before riding back down the road. Stopped at the saddle between Ptolemy and Hamilton and made a very quick trip up the SW side of Mt. Hamilton to the observatory. The observatory was still closed for COVID-19 and I was in full view of the security cameras, but no one bothered me. Then rode all the way back down to San Jose.
