Mike g ... i usually remove the 3 bridges that block access to the center if i am going back and forth a lot. Otherwise I just crawl under. Not too bad for a 6 -2 nearly 69 year old.
Regarding the buildings all have a 1st and 3rd floors. Have not thought much about the apartment building. I have reflective window film for the office buildings. Was going to see how that would look. Interior lighting is also undetermined at this point.
Got the elevated posts all glued up and will paint later tonight or tomorrow to give a 24 hour cure. Hard to wait.
