Day Four: Greens Creek (shuttle).  Today is our travel day over to Crested Butte, but we’re still going to get a solid ride in this morning!  Greens Creek has a 10-mile, 4000′ descent that’s best described as non-stop chunk.  Seriously, it’s unrelenting but it’s so much fun.  After the ride this morning, we’ll stop at the top of Monarch Pass for lunch and a post-ride beer, and then head over to Crested Butte to prepare for the second half of the trip.
