What is this tree/shrub, long white flower clusters? *Photos*?

Question

I have a tree or maybe large shrub (?) growing along my driveway, and am wondering what it is? It has lots of pretty white clusters of flowers.

So... Any idea what it is? =)

Answer 1

It appears to me to be a young cherry of some sort.  If it is, if you look closely at the leaf petioles (stems) you should be able to see small glands:  http://departments.bloomu.edu/biology/Ri...  An example of cherry blossoms on a wild black cherry:  http://www.missouriplants.com/Whitealt/P...

Privet is more tubular with 4 petals:  http://www.flickr.com/photos/jim-ar/4874... and the leaves are opposite - yours look alternate.
