I checked out the last Sunday Street SF event in the Richmond area yesterday. Weather was overcast with temperatures from the low to mid 60's. I suspect this was the reason why the crowds were not as dense compared to the other events I've attended during the summer months. Nonetheless, people still came out to enjoy the farmer's market, the food stalls, the local restaurants and stores along the route. There were many blocks both on Arguello and Clement streets that were empty. I had my bike with me so it was nice to ride peacefully along these areas.
