There's like 6 inches at the most between the mirror on the right truck and the truck on the left!
He had a few spare inches on the right (below), but there was stuff on the floor.
I was just so in awe that I had to go back to the house for the camera. It was so dark in there (partly because it was also dark and cloudy outside) that I didn't know if I could get good pics or not, but thanks to the DSLR, I managed to do it without a flash. (Kinda like trying to take pics of the moon at night.) It's really much darker in there than it appears in these photos.
Good job, my son! Proud of you I am!! ;)
