Megan walked in at 5:33 PM.
It’s 2.3 miles from our house to the Mountain View Transit station which takes 12-13 minutes to bike, plus some time to lock up and then we each still have to tag on with Clipper Card. The 5:57 North bound Baby Bullet arrives at 4th and King at 6:51 PM, and it takes 26 minutes to get from 4th and King to Fort Mason via Uber, assuming no wait for the pickup. Making the 5:57 PM train is basically a requirement to arrive by 7:30.
