Don't get adventurous at 3 a.m. and put yourself in jeopardy, whether driving or walking. That includes children, animals or cans of anything which might explode under extreme heat. Valet park your car whenever possible. Don't save a buck so you can get some exercise by walking through some parking garage with blind spots, loonies wandering through, elevators that take too long to go up or down and lack of security guards. Some parking garages are so isolated at some hours, that even if you called for help, no one would hear you or if they could, they'd react too late.
Many lots are poorly lit, contain confusing directions as to exits to the street or to the casino.
Whenever you're driving, at any intersection, don't be too anxious to be the first to show how good your reactions are when the light turns green. That extra second you hesitate might save your life. This city like many others is notorious for red-light runners who think they are too important to wait for the next sequence of green lights. Watch how drivers slow up and suddenly remember how vulnerable they are and how precious life is after they pass an accident or see a car pulled over and being ticketed. Yes, a taxi can be expensive, and a bus takes too long at times, but walking in dangerous neighborhoods or places you're guessing are safe, can be hazardous.
