Early in the morning, a few friends and I went to Mount Umunhum to watch the sunrise. The drive up was windy and somewhat steep, but fun.
We reached the front gate around 6:30 AM, finding ourselves unable to get in as the park did not open yet. Luckily, a construction worker passed us and let us in. We went to the first viewpoint just in time for sunset which overlooked the hills to the East of the Bay area.
There was a second set of gates, which we had to wait to open. This led us to a second viewpoint, with a large building and parking lot. There were some construction workers renovating an old building. We asked them what they were doing, and they told us that Mount Umunhum was a base for a radar during the Cold War. The construction workers were stripping the paint, which contained lead.
