Bird and the trees

It has been a tough time travel wise. Always weird when you fly back to home town for a few hours and not see your family. Anyways, on to more important things.. puzzle time…

Imagine a vertical tree 80 ft tall and a crow sitting right on the top of it. Now imagine a vertical tree 60 ft tall about 100 ft away from the first tree. The crow wants to fly to the top of the second tree BUT has to hit the ground once first enroute (essentially flying in two straight lines). What is the point on the ground it should hit so that it has to fly the least distance in all? 

Don’t worry about the dimensions. Think about the intuitive answers…
