Traveling light and comfortably is important. I use a mix of keychain items and stuff in other pockets.
>>Fox 40 whislte, with the round part filed down to make it smaller per Doug's recommendation
>>Boy Scout Hot Spark fire starter - smallest I've seen
>>ARC Premium AAA LED light, with a plastic lens cover from ACE hardware - more resistant to accidental turn-ons than a Photon
>>Ritter minigrip - relatively small, but a great knife!
Still want to carry a tiny compass, but have yet to find one I like, though have seen many. The Suunto Gem is closest to what I like, but the bezel on mine will hardly turn and the capsule falls out rather easily. I need something more reliable.
I need to get back into carrying bright orange 55 gallon bags with me for signaling and rain/cold protection- not in my pockets, but spread around in briefcase, desk, truck, etc...
I have first aid kits that go with me when I'm with the Scouts (my son's troop), and another one in my truck. I suppose I should keep one in my desk drawer too.
