Yes and no. The no it is not important answer is, I haven't gone in there in twelve years. There is 140 square feet of storage space - some only with 2 feet of headroom but others with five feet, back there, and I have gobs of old stuff and momentos there which I have managed to do without all these years.Where does the door go Lee? If you haven't missed it for all this time, is it really a necessary door?
No, all three of my tracks rise and fall about eight inches in the course of going around once. If you look at the next to last page (the view "an hour ago," the track in the foreground and the second of the two in the background are both the same loop: Mainline 1, but if you study the photo, the track in back is about 6 inches highter than the part in front.Wow! Is mainline 1 all the same level? No risers.
