So, soon my buddy and I will be heading out for a hike and our end destination is at I-40. My wife and kids will be there to pick us up, so I am wondering if the trail is marked easy enough for her to find it without much trouble and is there a spot for her to pull over and wait for us. I would like to try and plug it into my GPS for her if at all possible, just to make it a bit easier for her. Thanks for the help.
