eileen is right. You guys scare easily. My car was robbed in Woodley Park, which is about as Northwest as you can get. There have been shootings in Dupont recently.
Catholic is fine, so is the area around it. I go to church there on Sundays. Sometimes I drive, sometimes I take the Metro. Either way, I'm never scared of anything.
I personally think Adams Morgan is much more dangerous on a Friday/Saturday night at 3-4am than the area around Catholic, which is basically docile.
With regards to the NW signs, I guess that's a general rule, but many areas on NE and SE are improving, and will continue to do so. Have some faith. DC is coming back. All we need is a Mayor with some balls. This guy with his bow tie is pathetic.
