This weekend, we only had 90 minutes so we did a tandem loop from home (Campbell) to Lake Almaden and back through Willow Glen. 16 miles, with a nice stop for lunch at Alva's on Lincoln.

Thursday afternoon though, I climbed Montebello on the way home from work. What a nice climb that is! We were fortunate to have reasonably good air quality too.
