The picture is straight!!!
That a very steep hill! Gari haiwezi "hill start". So you build the road zig zag. Una-drive one direction, then back, on and on every time making some small upward gain mpaka ufike!!!
There are some roads like that [to small degree] in Sacho. Even in other areas in Kenya, you will find meadering roads where the land is too steep and you can't simply build a straight road! Luckily our land is not that steep and sometimes people don't even notice or care why the road is winding.
Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good returns.
