Ways to Save Money this summer

So, once again it's summer and I find myself with plenty of free time and less than plenty of money. Oh, I have some savings, but I have no full time job nor am likely to especially soon. More time, less money, means it's a great time to start refocusing on ways to save.

• Turn off the lights. Maybe turn off the computer too. It's amazing how much energy we waste during the course of a day.
  
  
• When I'm home by myself or when we're both going out, turn the air way up (or off altogether). I really don't like the way air conditioning feels, and I'm willing to be a little warmer. I can wear shorts or drink ice water. Also, I need to check the thermometer on my porch and open the windows when it's cooler out than in, and batten down the hatches when it's hotter.
  
  
• Hang my laundry. I've never done this before, but I'd imagine it'll dry very quickly in the 100 degree weather.
  
  
• Cook from scratch. During the crazy last month of the school year, we ate out a lot. A lot. I plan to change that this summer. I would like to go even further, though, and try making yogurt,cheese, pasta, and more of our bread.
  
  
• Use up the stockpile. I'm moving in the relatively near future so it's time to stop buying so much and start using it up. If I wasn't moving, I'd be reluctant to use up (or I might have to rebuy everything at full price), but I'd still try to use down a little to get through the income gap.
  
  
• Find fun, free things to do. Since we live near a college, there are lots of free lectures and forums, and I am relatively sure there are some free outdoor concerts and movies too.

Anyone have any more great suggestions on things I can do this summer?
