Cousin's Appalachian Trail thru hike!

Not sure if this is the right thread for this, but I've just gotta brag! My cousin and his wife (60ish yo) are currently in New Jersey on their thru hike of the entire 2160 mile Appalachian Trail! They started in mid-March and aim to complete it by the end of September. I was able to visit with them at a family reunion in PA a couple of weeks ago. He said it has been on her bucket list and they started planning and obtaining/testing gear two years ago. They actually live in Michigan and he is retired from the Coast Guard and she is currently a part-time RN. They figure their endeavor is costing them about $2000 per month, which includes gear, food, hotels (once a week) etc. She is posting daily video reports on Facebook, so family and friends can keep tabs on them, and so she will have a record of their adventure. Lots more I could report, but I don't want to bore you.
So...how awesome is that!?!?
