No idea. We usually do my house. My MIL is going to be in town that day, and H is working from home. My house may not be the best option, but I also can't think of a better place.
How about lettuce Lake Park, if the weather is nice? There is a $2 admission feel, but it's a really nice place. I love the playground (it's shaded too, if it's going to be hot) and the boradwalk is nice. Zoe loves to run around on it, or I push her in her stroller if she's tired. There are picinic benches so we can bring lunch, too.
Did I miss it? I fell asleep while I was watching Zoe this morning after work. H found me asleep on the couch while Zoe was playing with the DVD's, lol! Sorry I couldn't make it! This has been an exhausting couple of weeks!
