But don't let her into any McDonalds Play Areas. I used to play in one when I was little, but that thing was a death trap. A few weeks ago, I went over to it again. Hasn't changed. Still as grimy, poorly thought out in construction, and definitely dangerous as ever. Of course I didn't climb inside it - I'd have a hard time navigating the tunnels and... well, need I say more?
Point being, be mindful of playgrounds.
