I have no big trees inside my little yard, but I do have city trees outside our fence. In winter when the leaves have littered my yard, I get the much needed daytime warmth coming in thru our windows. Come summer, I have their leaves protecting us from the scorching heat...In Fall, they join the chorus of nature's color changing palette:
Summertime
Fall
Winter
And this other photo is around Lake Merritt in Oakland, CA, I just love the natural sculpture of this wonderful wind swept, gnarled tree!
