The Crow shit dilemma

You know what scares hostlers most ? Its the crows.
Our hostel is surrounded by lush green trees. Good isnt it ? Actually awesome. By evening a large number of crows perch on the trees. They rest till 5:00 am and then go back to work waking. While they rest they excrete. The road to the hostel is a patchwork of white on black. Of course the white colour is the crows work and the roads are cleaned regularly by sweepers.Walking to the hostel at night is a daunting task unless you like crow droppings. You can only hear crow shit hitting the ground and make a loud "SPLAT !". Its like a thriller .... there will be many near misses . If you are foolish enough to park your bike in the action zone your vehicle is bound to get a new look by morning. My friend's black R15 transformed overnight into a gorgeous 'R15 Dalmatian', credit goes to the crows team work. 

Now here is my dilemma. Should i walk on the black patches of the road or the white patches ??




CASE 1 : I walk on the black patches of the road


Why is the road still black ??  Coz there are no crows above or the crows above havent crapped yet ??


CASE 2 : I walk over the white patches

Should i assume that the crows above me have already crapped so they wont crap anymore ?


Right now im following Case 2 which i found is not fool proof. One crow successfully did its job........ :)
