Summer vrs Spring

As I was looking for a new picnic spot today on Google Maps I came across something that brilliantly showed the stark difference between Spring and Summer. This shows the satellite photos of an area near us where some of the photos are taken from the Spring (on the right) and some from the Summer. As you can see (and I'd recommend clicking on the image to enlarge it) there is not a speck of green to be seen in a Minnesota Spring (at least the early part of it).
