Of course it didn’t have a name then, and even if it had, the idea of the Ohlone Greenway was far in the future. At that time BART was planned but not yet built, and in fact the Southern Pacific Santa Fe tracks were in use until late in the 70s. A predecessor of today’s greenway was eventually built on the west side of the BART tracks, parts of which is still in use, but in the 60s the trail down the hill was better established than the one along the tracks. The Ohlone Greenway proper had to wait for the removal of the tracks.
It is very easy to miss this trail. On Liberty cars are often parked in front of the entrance. It is best to look for the end of the chain-link fence under a large, spreading oak. It is more or less across from the multiplex at 712-716 Liberty. At the bottom, the recent refurbishing of the Ohlone Greenway has left the entrance on the northbound (east) lane of the path just south of where it becomes one path again. Easy to miss, but worth a look if you are going that way. One Trekker member still uses it to go to the library, just as his brother showed him almost 50 years ago.
Write something about yourself. No need to be fancy, just an overview.
