San Francisco city is quite hard to cycle in. Drivers just don't seem to notice cyclists one way or another. More difficult than expected is to fully stop at the stop-sign for no traffic. After some finetuning edge is doing great with a local T-Mobile simcard in the EU-smartphone. My US number is (415) 646-6921. Touring next to the harbour was more relaxing, except for the wind.. Tomorrow I'll go for a tour around the north part of the SFO-bay.
