I have never seen Lilac flowers in Santa Clara or Sunnyvale.. but there are at least 4-5 houses on the street here with Lilac flowers..
This is the closest I could get with my macro mode on the S30.
The best part is that we are at the base of a hill and we have deer coming to our front yard to eat the lilac flowers !! (will post a picture of the deer soon).. Planning to spend this saturday deer chasing !
