i never carry a wallet with me either, and it works pretty good anyway. i never bring money with me except when i need a few bucks and its always in my front pocket.
i dont understand people who put shit in their back pocket? can someone tell me...
only stuff i remember losing is a few coins when i sit down in a car and a pack of starbursts, and i was really pissed for that 1$ starburst candy... hah
