This year I've been making a concerted effort to "commute" to group rides rather than drive my truck. It adds another 20 miles to the ride and helps further reduce my driving. I was just running the numbers on my cycling log and was really surprised what a difference it has made. So far, I've ridden an extra 420 miles than if I had driven. It's also a great way to get in some long rides since most of my cycling buddies seldom want to ride more than 40 miles or so.
