This was one of the coolest things I have seen at the park. A quick google search will show that the custodial team at TDA has been at this for a while, but with as much time as I have spent at the parks I have never seen this!
We had just finished out Fantasmic! 20th anniversary showing, had already ridden on Big Thunder Mountain and were headed to Pirates… when we saw a few people admiring something on the ground. We saw some water on the ground and as our eyes adjusted to the ground in front of Riverbell Terrace, we realized that it was artwork!
Here are some pictures we snapped of a few of the characters drawn on the ground and to boot, I caught some video of the cast member drawing a huge Mickey Mouse in front of Pirates! Enjoy!
