yeah, Presidio is a fun map.
weird thing happened last night though; was playing some Team Survival with a friend and some other guys, and when the host switched maps to Red Lotus it said I didn't have the DLC to play. of course that wasn't true, as I have both map packs, but for some reason the game didn't see them on my drive. I had to restart my 360 for the game to see the DLC.
so just a warning, if that happens to any of you, you don't have to download the packs again, just restart your 360. my buddy said it happened to him on COD2 a lot, and he's the one who told me to restart.
