Nah, maybe he could have stuck his head in the pink one but they are really only like 6 - 8" diameter pipes. I think it is a trick of perspective going on there, now that I look at that picture again they look much bigger than they are. There was some larger black ribbed pipe to line a culvert that they crawled through but I didn't get pictures. Construction sites are a lot of fun. Right as we were getting into the car to leave a truck pulled up that I think was coming to check on us and tell us to get out of there, as we pulled out the truck just did a uturn and left.
