No GPS!

My son continues to amuse us daily with his thoughts and ramblings.  But I was really amused the other day and just thought I would share...  As I was folding clothes, Blaine was "planting" the carpet.  Suddenly, he stops and says "Uh oh Mom - this tractor doesn't have GPS!"  So he proceeded to put his guide markers down and then trade for a different tractor that had the little yellow GPS receiver on top:)  What 3 year old talks about GPS and auto-steering on his toy tractors?!
