*after flying few miles

In: Biology

Answer 1

Roadnames and signs and stuff are not the only landmarks available for navigation.

Imagine yourself in russia with all the street name,signs and directions in unreadable characters. You would chose different things as landmarks, like that big tree down the block, or the funny looking house around the corner and stuff like that. Or the small river a few minutes walk past the big tree.
