They watch for us...
Hmm... one thing about the sidewalk on 12th. The customers at the coffee shop and restaurant are saavy, but I'm looking over my shoulder at traffic. Not a good mix if I'm still rolling. So ride to a safe spot (looking forward), stop, wait then go during the break.
I like getting on 12th proper as well from the left turn thingy, but if I'm more than say 4-5 cars back from the stoplight it's tough not to impede traffic as these folks tend to hit it hard on the green.
