Day 3

Yesterday, the 27, I could not get on the blog.
Because designing walkways needs a model to be completely worthwhile, I didn't do much.
I did have the idea of 2 macho major ramps looping outside of the 'circles'.
They would start on one end of the circle, rise and spin around the circle and connect on the oposite side, so the entrance and exit would be on the same 'chord' of the 'circle', just on different levels. The length a person would end up walking to get to the next level would be about 160 m, based on my math.
Go Pythagoras.
There would be 2 to connect level 1 and 2, one on each 'side' of the circle level, and 2 for 2 and 3, offset slightly so that as you walk up from 1, the entrance to level 3 is right there one you reach 2.
...It makes sense to me.
That was day 3.
