Campgrounds2k8 is a gorgeous map, but it has some serious collision problems.  I recommend [url=http://utforums.epicgames.com/showthread.php?t=605834][color=red:f1b1f48356]DM-Campgrounds]I[[/color:f1b1f48356][/url].

I really think you should add [url=http://utforums.epicgames.com/showthread.php?t=602751][color=red:f1b1f48356]DM-Casablanca[/color:f1b1f48356][/url].  It's a really fun map with numerous sniper perches.  Jump pads to these perches provide skilled snipers the chance for a mid-air shot while people try and get to the perches.  A central tower is surrounded by fabric awnings that act as springboards.  Tons of fun!
