Hi everyone i joined the forum a little over a year ago and have been enjoying reading all the great posts. This is my first o gauge layout and i am inspired by all of the outstanding layouts and the wealth of knowledge on this forum. Our house does not have a basement so i decided to use our attic for my layout. it took me about three months to re-due the attic, i framed two knee walls to close off the sides,installed insulation,drywall,new electric and a HVAC unit. i am not modeling any specific area or time frame i am just enjoying the ride. I will try to post a video of my layout so you can see where i am at with it. thanks in advance for any comments.
