jOe's measurements and geometry both suspect. Bricks in this little Piggy's house measure 2 1/2" including mortar seam. That would make the Laird's tubes about 28 3/4" and considering a bit of length is getting chewed by crossing the unit of measurement on the bias, 30" sounds about right. Saw one at Millbrook, Lowell. No bricks available for a scientifically-based evaluation but I was able to establish the price after counting zeros for awhile.
