Since I am now walking on a fairly regular basis, I decided to put a walk pack together. Just used a small, sport sling backpack. I hate keeping a lot of stuff in my pockets, and sometimes don't even have pockets. It's ready to go on a moments notice by the door.
Items in mine:Rescue inhaler & glucose tablets (I'm diabetic & asthmatic); Special house key on a lanyard (special because I got a fun lanyard and matching key, also has my Medicalert dogtag on it); my phone, water bottles for me & my dog, umbrella, sunglasses, good girl cookies for puppy, ipod band
