Welll nowwww..... you want to store the bird in a metal box or wooden one... smile....
go to the site listed below and you will be able to see some of the others that are around the country... one of which I think is right up where you live...

Schweiss is the door manufacture located at
http://www.bifold.com/
I have about 50 feet of frontage and the door is 45 ft long... so that it will have some room for a side door .. don't want the door in the bi-fold part...
Ya they get pretty expensive to build.. and of course you can consolidate.... but, just think it will be in your living room.. that way you can watch movies like Bat 21... on the big screen TV... make gunfire noizes from the computer... and sit in the real thing.. while your wife makes dinner... smile... Ya I know the prop gets in the way.... when its not runing... but, then again... you can have a whole house cleaning and airconditioning by breeze once you fire up that little bueatie.... and just think put two doors on it and you can drive thru.. no backing up needed... think of the money you will save... no tug... no vacuum cleaner... no airconditioner... why what a savings... of course she may not like you getting the oil on the rug... but, put news paper down before yo start... just think of the money you save... smile....
