Just turned 50; also getting back to it after about 30 years. I'm looking forward to trying out the newer light packs. I keep watching the developments in lighter, thicker sleeping pads-as a side sleeper with Hips I want depth for comfort. Right now all I can manage is day hikes, but in a coupla more years look out! I am trying to take good care of my joints so they will still be good to go when I am.
