This hike is listed as a shuttle hike but with no one to assist with the shuttle; I just made it a round trip. Actually wanted the mileage for endurance training anyhow. From the First Water TH to Freemont saddle, I probably had contact with 5 people and it was a wonderful hike. However, from the saddle down to Peralta TH and back up to the saddle, I probably passed 150! It was like a circus with unruly dogs, disobedient children, "runners" yelling to get by, "Frat Packs", cosmetic enhancements, men hiking up to the saddle with guns, and at least a half dozen guys who looked to be flirting with heart attacks by the color of their complexions. Once clear of the saddle, the next 9 miles back to First Water were great, passing 5 to 8 very pleasant hikers. Overall, a beautiful day of hiking.
