As we decided to leave, it poured. We were trapped in the center for a while and when the rain stopped, we left the center, only to be trapped by this little river that formed from the rain. We were separated from the main road by this river (the road in the picture is not the main road and no car was driving on this road. The main road was next to this small road). We ended up walking for another 30-45min to get to an intersection where we can cross to the main road and get into a cab. Overall, this whole science center trip was a total disaster!!
