Just finished my second full week of bike commuting. I have learned to pace myself and cut about 8 minutes from the commute, even if I feel like am riding really slow.
I have been doing some window shopping for a new bike, but have so far been able to resist the temptation. It is just that those little things that don't work properly on your bike start to really bother you when riding over an hour per day.
The balance of the week: saw the aftermath of an accident involving a bike rider and a car. Interesting or rare cars seen include a Skyline GT-R, C63 AMG, 911 (some sort of 996 GT or something) and a 308.
