If you can put up with wackos, and a limited riding season, Portland, Or. Fantastic riding, that you’ll never run out of ideas. The summers are great but limited to 3 months. But, during that period it never rains. So, you probably get more riding in those three months than most places in the whole year.

Although it seems to be growing too fast for my tastes in the areas of traffic and people, Denver is a good combination of both of your elements. I live in a western suburb of Denver and can be either deep in the mountains or in the center of downtown Denver within 15 minutes of my house. I have to admit I take it for granted but when I feel like going on a ride, I get as much of twisty mountain roads with awesome scenery as I want. And Denver seems to have most, if not all of the comforts of a large city.
