For the most part, there's some good advice going around here. The only thing I could add is just to make sure that everything is manageable in your pockets and is comfortable. For example, I carry a deck of cards, three nails (blockhead), occasionally some razor blades and string(for eating), a magicians copper coin (Rick, you may be familiar with the Mundus Vult Decipi : Decipiator coin), and if I'm feeling silly and crude, two black four inch sponge balls behind my zipper. not one of these things is uncomfortable, and as an added bonus, the sponge balls pump up my junk. As for Rick, he must be wearing parachute pants to hold all of his stuff, in which case I will refer to him as "white hammer time".
