Going Shopping

Our first full day in San Francisco. We are in charge of Autumn, our granddaughter, with no opportunity to shake off the jet lag. We decided to walk to the shops, which is a brave decision in this district - it's steep and its hot. OK on the way there, because it's downhill, but on the way back with full shopping bags and a 3 year old?????
The bonus of being in the Potrero Hill area is that we get fantastic views of downtown San Francisco & the Bay Bridge.
