Planning on taking BART from SFO to Powell and then walking to Hotel Chancellor. When riding BART is the train layout so that my medium size luggage and carryon stay right beside me? Is BART safe to ride regarding type of people riding the BART? Are BART stations relatively safe? Also, as a male, is the best place to keep my wallet in my front pocket of my jeans? (Concerned about Pick pockets) Just trying to stay safe!
