C'mon, it gets dark everywhere sooner or later! Most cameras will have a manual setting to turn off the flash. Without the flash even on auto the shutter speed will slow down a bit. The key is having the camera on something stable. You don't have to have a tripod anything will work. I've used garbage cans and hoods of other vehicles. I've even set cameras on top of coke machines and walls. If your camera has a selection for shutter speed, go in and slow it down. The slower it gets the more crucial it is that your camera is stationary. Keep slowing it down til you get the effect that you want. With a long enough exposure you can make midnight look like mid day. Get out there tonight and shoot some more pics!
