    "My neighbourhood has awful access to public transport. I don’t have a car at the moment. If I want to go into town it’s an hour & 20min walk both ways. It keeps me fit, I guess. We just moved here from Chicago, so it’s a bit of a culture shock. I survived 8 years there with no car. 3 of those years were with kids. The first week we were here, I thought I’d take the kids into SF to see their dads new workplace. I walked for 40mins uphill, pushing a stroller with my 3.5yo and carrying my 1year old on my back so we could catch a bus from St Mary’s College (that runs very not very often) to Orinda BART into SF. Not an experience I would repeat. We probably should have just walked into Lafayette and got the BART from there I need to get my UK licence changed to a CA one, so I can get on the insurance to drive my husbands car"

    "When the power transformers explode, a line comes down, a neighbor has an accident, the tree cutting service smashes into the fire hydrant and floods my garage with water, a cyclist gets hit by a car and the kids run around at halloween, everyone comes together pretty quickly and there’s always people around during the day to help. Seriously good people but mother nature and other factors definitely keep it exciting."
