Forum:Does Anyone Know Some Places To Camp In Xbox Live

DOES ANYONE KNOW SOME PLACES TO CAMP ( MW2 ) ON XBOX LIVE
So I kind of got my Xbox Live account hooked and I full out suck at Xbox Live MW2 which is also my favorite Multiplayer game. I know how to stealth but I need some tips. If one of you can post  a comment on WHAT MAP the camp spot is located on, What kind of strategy it desires, and if it is always gonna be WELL populated. For Ex: ( The sniping spot in Jungle where u climb up that little hill and kill anyone passing by) No, I don't want any well populated and well known areas. I am mostly about machine gun sniping, not sniper rifile sniping. I also want to know how to CHANGE your Xbox Live gamertag name. For Ex: my gamertags thing is, Roomyhorizon1 -_-. I want to know also how to change that. Thank you to all the people who are gonna give me some tips and how to change the gamertag name :D BYE
