Wow, 19 days and no lines!
I enjoyed Foothills Park in Palo Alto many times. They blocked off the parking lots, so I had to park a mile away and walk in. But I had 1,400 acres all to myself and the normal constant jet traffic overhead headed to SFO was completely gone. The freeways were empty, too. Just blessed silence!
I still have a full 16 oz glass bottle of Coca Cola I found in Foothills Park on a hike back in 1981. It was shallowly buried in the ground with tree roots growing around it. I thought I was seeing things, but I had caught a glimpse of the logo on the glass. Who knows how long it had been there before I dug it out 41 years ago.
