In Oregon, on average, there are more days in the 40-60F range, waiting for days over 60F would mean the bike sits most of the year.

Actually, I really enjoy the seasonal changes in weather and having the right gear allows me to ride all year in relative comfort. Call me strange, but riding in cold or wet rain while protected from the elements with the right clothing is extremely enjoyable and gratifying. Also takes me back to my youth; where I feel like a kid once again without a care in the world. In other words, it can be downright FUN!
