A marble run is one of those classic toys that every little boy has to have, don't you think? I first saw a homemade marble run similar to this one at a friends house and knew I had to make one. And with Joe's birthday coming up, the timing couldn't have been more perfect. Unfortunately I didn't take pictures along the way... so if you want to make one, you can do the same thing we did and wing it (sorry). But I do have to give Pete the credit for this one. He bought the supplies, measured everything out, and put the screws in... so pretty much everything. I sanded down parts, stained it, and helped with the measuring. All I know is this thing is a rock! Pete built it knowing that 4 little boys would be playing with it for many years to come. Well done Pete.
