Sandboxes and such

I bought Kaylie a turtle sandbox about a month ago or so, and she enjoys it so much! I don't have any pictures to show right now, but there have quite a few times that her daddy joins her in there when he gets home. It has been a great entertainer!!!!
In the same week that she got the sandbox, she learned how to 'belly-swing' on the swingset and how to climb up on her 'baby' swing, and figured out how to get the t-bar up and strap herself in. Which then meant she calls for me till I happen to look out at her and realize she's stuck and waiting for help.........So basically all in a week's time, she figured out how to do everything on her playground out there--sandbox, two big girl's swings, her own baby swing, the rocket glider (she'd been working on that one before) and of course the slide she'd been doing. The nice part of this is--it used to be she could do nothing but the slide, so she wasn't entertained out there for long at all with her several toys. Thankfully now she'll spend multiple minutes out there, generally as long as I let her.

How many of you have 'bought' sandboxes? Or do you have a wooden/no lidded 'home grown' sandbox?
