You really need a car. A small town of less than 1800, there is no public transportation and in the east end of town not even any sidewalks. A bike can work, but getting out of town there are lots of hills and the weather can change really quickly. You will need AC in the summer. In the winter, there is usually snow on the ground and probably ice as well. Having snow tires is the best, but chains are always a good thing to have in the mountains, and alot of the time you need them to cross Snoqualmie Pass.
