Another question, is it acutally possible to work at more positions and put the "parts" together at the end?
I think it will be to much work for one person. 
yes, mark 'districts' on this map (like gangs areas) so we can know who make what, later i can put all in one

you have to go aroung the pylons, or the bumbs...
Or this will happen.
about bumps, ask Ush, he is bumps specialist
