Go for a walk

Eh, you could get your sister at any time. What's life without a little variety once in a while?
"Beth, I'm going out." You call, getting a mumbled 'kay' in response. Leaving the house, you get on a bus heading downtown. After a twenty-minute-or-so ride, you get off and start wandering around, frowning. Where could you go to have some fun that wouldn't be...suspicious?
