Good topic idea! I'm fascinated by trees. There are two gigantic locust trees in my backyard shading our deck. I love those, but they shed a lot of crap. I'd like to see the Redwoods someday, they are incredible. The palm trees along streets in LA amaze me as well. Oaks like the ones in the picture are cool, too. There's a gigantic one downtown George Washington used to sit under. I'm basically a huge fan of gigantic, widespread trees that create canopies. There's a section of road down the street that is completely covered by trees very high above the road itself that I just love.
You might not know this, but those oaks in the pic are 300 years older than the house they frame. The house planned by the Frenchman who planted the trees, had to put the house on hold due to circumstances.
