My 3 sons, ages 17-21, have agreed to go on a "man trip" with dad. We have decided to go on a 3-4 day hike, but the boys want something challenging. I want a trip they will remember and am looking for a hike that is a combination of adveture and majestic. A friend suggested the Shenandoah area of the AT, but I am open to anything within a days drive of Illinois. I am looking for advice from experienced hikers, and I thank you in advance!
