Rainy Day Car Play!

I was just flicking through posts in the morning and I found this great idea for the ultimate rainy day activity that I just knew we had to do at some point... It just happened to be a rainy day here so I thought 'why not now?'
However I altered it slightly as we have an outdoor craft area and I thought that it would be cool to have it as a permanent feature and play space..
All we used were:
☆ Oil pastels
☆ Crayons
☆ Our Imaginations
This was how we did it..
I cleaned the ground.. it could have done with a wash after all our playdoh and slime activities but hey, I only swept as I wasn't going to put that much work in, HA it was Sunday after all and we were being slightly spontaneous so the kids went going to hold out that long before becoming restless and cheeky :P
(I figured I would just add it to my list of things to organise/finalise without the kids around)
I started our drawing the road and told the kids to go and get the cars. They were very intrigued that I was drawing on the ground and ran off to get them.
When they came back there was an outline of a road I told them what I was doing and immediately they wanted to join in creating the city..
Naite wanted an army base so he set off planning where that was going to be and created that.. I helped Leila to draw a park, city and houses while Amelia well.. chewed on cars :P
The kids then spent sometime driving the cars around and racing before it lead to needing a few more things for their game we ended up with:
A carport, an airport, a runway, a army base, police station, communication satellite, machanic, city, homes, park, ambulance station, hospital and shops..
Naite even worked on his writing labeling the police station, hospital and fire station! And he did a great job his writing is getting much clearer :D
They spent hours playing, creating and role playing oh and chewing cars! Even Charlie joined in Amelia and Charlie were giants destroying the city! LOL
And now, seeing as we used crayons and oil pastels to draw, when I wash the ground it will not only stand out more but I imagine that it will be added to and continued to be played with long after the rain has disappeared :)
Thanks again to 'how wee learn' for the fantastic inspiration!
