Hobbies for couples with a baby

Amanda
Hi everyone! I'm looking for a hobby that my husband and I can take up. We have a 6-month old daughter and money is tight. I'm looking for ideas of cheap places to go or things to do that we can bring a baby to. We sit around and watch a lot of tv, and I want to get out of that habit.  I'm looking for something to do (or somewhere to go) when she's awake, and activities/hobbies that my husband and I can do for fun at home after she goes to bed. What do you do for hobbies with your significant other?
