I haven't changed much. Had a Leatherman on my belt pre 9/11, flashlight in the glovebox and jumper cables in the truck. 9/11 just gave me some assurance that I was doing the right thing and that allocating some budget to supplies like that was worth it. I might have stepped up my preps some but I can't say for sure if that was due to 9/11 or just my natureal progression.
