Good for you Wayne! I got a little freaked out when I shimmied into my oven (face up) for the first time. I felt totally claustrophobic and my heart started to jump out of my chest.
I had to tell myself, 'It's ok Rick, you're not in some Crypt, you're just in the dome you built!' After awhile it got kinda' peaceful and pretty comfortable!
I did however, need to keep one hand on the outside arch as a security blanket!
(Actually the only way I could fit through the door was one arm over my shoulder and the other down by my side.) I was hoping my wife wouldn't come home and have to pry me out with a giant shoe horn!!! Tell Neil you owe him Pizza(s)!!!!
