Guthooks is awesome!
Get some motivated, self sufficient friends and go for it! You cant get lost. No guide required!
No need for a guide. The trail is uber marked. Almost impossible to get lost unless you try. At this time of year you will not be alone on the trail no matter the direction you travel, north or south. Best thing if you want company is to just make friends with those on the trail. Most are very friendly and always willing to offer advice.
What exactly are you looking for? A guide to actually guide you, a group to join up with as they hike or what?
