| Hi Dave
Although this being yd i'm sure some one will be along to correct me with mm perfect dimentions(yes i've got my tongue in cheek) the tunnel at 24 is only 4m long or so and you can see all the way through it , the one at 55m is 10m plus i think ( bit fuzzy yesterday) and it has a bit of a dog leg in it .
neither have lines running through them AIRC |
