Beautiful Day

It got to 75 and sunny today with beautiful blue sky and very white clouds. This tree  is blooming with lovely white blossoms. I have to idea what it is. 
We got a good dose of fresh air and vitamin D as we sat in our driveway trying to pop the hood on my car and then waiting for roadside assistance to jumpstart my dead battery. I need to drive my car more than every 6 months from now on.
