I've also added a tourist map of the city that includes all transit routes, taxi numbers and local hotels. Enough cash for a night in a hotel is going in my wallet too. I don't know anyone who lives in the city anymore and might need somewhere to stay if snow should hit in a few months.
1 - I suggest you share these plans with your husband even if he doesn't accompany you in these trips. If something bad happens ( like snow ) he will know which hotel you will be heading to. During a snow storm , communications maybe off and you may not be able to contact him.
2- You can also save maps as images in your cell phone. It's convenient and good backup. But paper maps should be there too ( one copy for your husband too).
3 - You don't know anyone in the city , but you can start to know someone. Maybe a cap driver, a nurse in the hospital, anyone who is likely to offer help for money or free.
