In May we're planning to ride from our place in San Jose down the coast to San Luis Obispo and then taking the train back home. Let's hope they repair the road south of Carmel for the upcoming Pacific Coast touring season.
In October we're thinking of riding the Adventuring Cycling Utah Cliffs Loop.
I agree that short tours are also fun. Although we dream of the epic tours, it's the week-long tours a couple of times a year that keep us content.
