My kids had a blast during train week.  Hands down, their favorite thing, was using trains to paint.  We put paint on our paper and then used the wheels of the trains to run it across the paper.  The paintings were all so different and the kids had a blast with it.  They also loved their conductor uniforms and the ride in to Austin on the metro.  Definitely a fun week for us!  Even Ty joined in by setting up different train track areas in the house for the little kids.
