How do I keep summer fun?

So I haven't updated for awhile 1. Because we have had some computer issues 2. My camera needs new batteries, and I pretty much need a new one anyway and 3. We are very boring around here. I feel like I need to have something interesting to say so I don't waste anyone's (The 3 people who actually read this) time. Well...life isn't getting interesting anytime soon so what can I do to make summer fun? I told my kids before school got out that we could plan 1 fun thing to do a week through the summer. I wish I had more energy to do more than that but that isn't going to happen this year. I am also on a tighter budget this year so I need some ideas. We are done with Discovery Gateway(we had a pass last year and my kids need a break from it) but other than that I would welcome any ideas. Some things we have planned include 1. Going to the fountains at Gateway and Liberty Park 2. Of course Wheeler Farm 3. Going with Suzanne to Thanksgiving Point. Any ideas(especially free would be great) I feel like I don't want to let my kids down this summer. It has been a rough few months and they have been little troopers. M and L have learned how to do their own laundry and have been really good helpers. I feel like I need to really get out there and make a stronger effort to have fun with them. I feel like a slacker lately.
